Fix GC hole when exception filter throws unhandled exception (#9785)

handles the difference in the exception stack unwinding on Unix was not
skipping exception trackers belonging to filter clauses. But that was not
right, since filter funclet stack frames behave the same way on Windows and
Unix. They can be present on the stack when we reach their parent frame if
the filter hasn't finished running yet or they can be gone if the filter
completed running, either succesfully or with unhandled exception.
This change adds skipping of filter funclet related exception trackers at
that place so that the common code processes them.

running some tests with GCStress mode 2.

Fix incorrect cast in gtFoldExprConst
The fact that an operation is unsigned affects the operation itself but that doesn't mean that the result of the operation is also unsigned. Constants are stored as ssize_t and the node type is TYP_INT so the result has to be sign extended, not zero extended.
Otherwise code that uses the return of IconValue() without first narrowing it to int will behave incorrectly. Such code does exists, even gtFoldExprConst does this when folding shift operations:
uint a = uint.MaxValue;
uint b = 0;
int r = (int)checked(a + b);
Console.WriteLine((r >> 2).ToString("X"));
The above code prints
3FFFFFFF instead of the expected
FFFFFFFF.
This also makes gtFoldExprConst consistent with ValueNumStore::EvalFuncForConstantArgs which evaluates TYP_INT nodes as int and then casts to ssize_t.

* Address some code review feedback:
1. Make g_gcDacGlobals a pointer and dacvar on the VM side, so
that publishing the GC dac vars is done atomically (through
a pointer assignment). This fixes a race that Noah noticed.
2. Remove the requirement for the GC's generation class struct
to be known at compile-time, by using a dacvar as the size
of the generation class at run-time (for pointer arithmetic)
3. Move all DAC-interesting fields to be at the start of GC
internal classes, so that the DAC does not need to know the
size or exact layout of the class past the fields it cares
about.
* Split the definition of the size of several arrays across the SOS/DAC and GC/DAC interfaces, and add static asserts that they are the same
* Repair the Windows Release build
* Implement the GC DAC scheme for Server GC and eliminate the duplicate GC dac vars

Add jit test project checker as jit test (#9721)
Add the tool used to fix/repair projects as a test case. It will
fail with an error code if any project file in the jit test subtree
needs fixing.
This test requires CORE_ROOT to point at the test overlay and
that directory be rooted under the repo (other test cases already
have similar requirements).
CodeGenBringUp tests are noted as needing fixes, but are accounted
for under the category of "deferred fixes".

JIT: defer setting outgoing args size until after optimization (#9683)
For fixed out args ABIs, the jit currently computes the size of the
out arg area during morph, as it encounters calls that must pass arguments
via the stack.
Subsequently, the optimizer may delete calls, either because they are
pure and the results are unused, or because they are conditional and the
guarding predicates are resolved by the optimizer in such a way that
the call is no longer reachable.
In particular if all the calls seen by morph are subsequently removed by
the optimizer, the jit may generate a stack frame that it never uses and
doesn't need. If only some calls are removed then the stack frame may end
up larger than necessary.
One motivating example is the inlining of a shared generic method that
ignores its generic context parameter. The caller typically must invoke a pure
helper to determine the proper argument to pass. Post inline the call's result
is unused, and the helper call is deleted by the optimizer.
This change defers the outgoing arg size computation until fgSimpleLowering,
which runs after optimization. The code in morph now simply records the
needed size for each call in the associated fgArgInfo.
As before, the outgoing arg size computation ignores fast tail calls, since
they can use the caller-supplied scratch area for memory arguments.
The jit may introduce helper calls after optimization which could seemingly
invalidate the out args area size. The presumption here is that these calls
are carefully designed not to use the caller-supplied scratch area. The
current code makes the same assumption.
This change introduces some unanticipated diffs. Optcse estimates the
frame size to decide how aggressive it should be about cses of local
variable references. This size estimate included the out args area, which
appears to be something of an oversight; there are no cse opportunities
in this area and the offsets of the other local variables are not impacted
by the size of this area. With this change the out args area size is seen
as zero during optimization and so the cse strategy for a method may be
different.
