Display the arm instruction size
When dumping an arm instruction, and when we don't have the actual
code bytes (such as during code generation, as opposed to emission),
display the (current) instruction size, either 2 bytes (2B),
4 bytes (4B), or 6 bytes (6B).

Update maximum allowed arm prolog size
Change #23715 changed the localloc stack probe loop to load a
negative constant instead of zero to start the probing loop.
This increased the size of the probing loop, and hence the
size of the maximum prolog, by 4 bytes. Bump the assert on
the maximum size to match.
Note that as the comment says, the maximum size there is not
actually a maximum (it was originally), it is just to alert
us when the maximum generated prolog size has gone up.
Fixes #23920

Second, it fixes argument validation so that we throw an ArgumentNullException if the input array is null rather than NullReferenceException.
Third, it improves the performance of `GetSubArray` for the 95% common case where either `T` is a value type or the type of the array matches the `T` type specified.

Don't null out references in Stream/BinaryReader/Writer (#23725)
These types null out some fields on Dispose, and some of those fields are accessible directly via exposed properties, which means that nulling them out would either force us to annotate those properties as being nullable or would require us to lie about them being nullable. Nulling them out also makes it easier to accidentally null ref in the implementation, and prevents us from making the fields readonly.
It should be exceedingly rare that you dispose of one of these objects and then keep it alive while also being concerned about keeping alive the other helper objects the type uses. So this change just uses a separate flag to track disposal, and avoids nulling out the fields, which is not a common practice elsewhere in the framework.
This will be a visible change in that after Dispose, properties like StreamWriter.BaseStream/Encoding will now return the stream/encoding rather than null. In theory that could break someone if they were using those properties to determine whether the writer had been disposed, but that seems unlikely / similar fallout from most any bug fix, and objects generally aren't supposed to be touched after Dispose, anyway.

Partially improve support for `--cpus` from Docker CLI (#23747)
* Round up the value of the CPU limit
In the case where `--cpus` is set to a value very close to the smaller
integer (ex: 1.
499999999), it would previously be rounded down. This
would mean that the runtime would only try to take advantage of 1 CPU in
this example, leading to underutilization.
By rounding it up, we augment the pressure on the OS threads scheduler,
but even in the worst case scenario (`--cpus=1.
000000001` previously
being rounded to 1, now rounded to 2), we do not observe any
overutilization of the CPU leading to performance degradation.
* Teach the ThreadPool of CPU limits
By making sure we do take the CPU limits into account when computing the
CPU busy time, we ensure we do not have the various heuristic of the
threadpool competing with each other: one trying to allocate more
threads to increase the CPU busy time, and the other one trying to
allocate less threads because there adding more doesn't improve the
throughput.
Let's take the example of a system with 20 cores, and a docker container
with `--cpus=2`. It would mean the total CPU usage of the machine is
2000%, while the CPU limit is 200%. Because the OS scheduler would never
allocate more than 200% of its total CPU budget to the docker container,
the CPU busy time would never get over 200%. From `PAL_GetCpuBusyTime`,
this would indicate that we threadpool threads are mostly doing non-CPU
bound work, meaning we could launch more threads.

Fix SystemV AMD64 Explicit structure classification (#22041)
* Don't bail out on enregistering explicit structs if there are no overlapping fields.
* Don't enregister if any unaligned fields.
* Enable passing explicit structs by-value by enregistering on systemv. Some edge cases are likely still broken, but just removing our blanket opt-out makes the current tests pass.
* Enable MarshalstructAsLayoutExp off-Windows.
* Start adding additional tests for explicit layout to try to catch edge cases in SystemV classification.
* Added a test that spans across multiple eightbytes and has an overlap in the second eightbyte.
* Change repro to use an array of floats and an int field in managed and use a float array for padding in native to force an SSE classification on the first byte.
* New algorithm to calculate eightbyte classification by going throw the structure byte-by-byte instead of field-by-field.
* Fix updating eightbyte classifications in the loop to actually used the iterated-upon variable.
* Consider each element of a fixed array as a separate field (to match native implementations).
* Implement correct SystemV classification for fixed buffers in non-blittable structures. Fixed buffers in blittable structures have the managed layout assign classifications, which still is buggy.
* Add tests.
* Correctly classify blittable fixed buffers. Move "is this field a fixed buffer" tracking into one of the unused bits in FieldDesc as code that isn't in marshalers needs to know about it.
* Handle the case where we have a struct that has no fields in an eightbyte that contains (i.e. no fields in the first eight bytes of the structure).
* PR feedback.
* Only look up FixedBufferAttribute when the type is a value class and the type of the field is a value type.
* Use heuristic to determine if a type is a fixed buffer for SystemV classification.
* Revert tracking if a field is a fixed buffer in the FieldDesc.
* Update comments.
* Classify aligned, nonoverlapping, float/double only structures as HFAs even if explicitly laid out
* Enable overlapping fields in HFAs. Update NativeType HFA to check for alignment.
I checked Godbolt to verify that HFAs for overlapping fields are allowed.
* Add HFA tests.
* Fix compile errors from HFA alignment check.
* Non-valuetypes will never have their managed layout used to classify SystemV eightbytes.
* Don't classify a struct with no zero-offset field as an HFA.
* Remove duplicate semicolon.

* Fix signed/unsigned mismatch
* Fix condition to also detect arm64.
* Change ifdef to if defined.

* Add some logging in one of the unreproable OSX test failures.
* Mark System.Numerics.Vector as intrinsic and don't use the eightbyte classifier to enregister it.
* Also explicitly opt-out of HFAs for System.Numerics.Vector`1 for consistency.
* Update R2R required version to 3.0.
