[mlir][Analysis][NFC] Split FlatAffineValueConstraints into multiple classes
The new class hierarchy is as follows:
* `IntegerRelation` (no change)
* `IntegerPolyhedron` (no change)
* `FlatLinearConstraints`: provides an AffineExpr-based API
* `FlatLinearValueConstraints`: stores an additional mapping of non-local vars to SSA values
* `FlatAffineValueConstraints`: provides additional helper functions for Affine dialect ops

`FlatConstraints` and `FlatValueConstraints` are moved from `MLIRAffineAnalysis` to `MLIRAnalysis` and can be used without depending on the Affine dialect.
This change is in preparation of D145681, which adds an MLIR interface that depends on `FlatConstraints` (and cannot depend on the Affine dialect or any other dialect).

[libc++] Remove availability markup for std::format
std::format is currently experimental, so there is technically no
deployment target requirement for it (since the only symbols required
for it are in `libc++experimental.a`).
However, some parts of std::format depend indirectly on the floating
point std::to_chars implementation, which does have deployment target
requirements.
This patch removes all the availability format for std::format and
updates the XFAILs in the tests to properly explain why they fail
on old deployment targets, when they do. It also changes a couple
of tests to avoid depending on floating-point std::to_chars when
it isn't fundamental to the test.
Finally, some tests are marked as XFAIL but I added a comment saying
TODO FMT This test should not require std::to_chars(floating-point)
These tests do not fundamentally depend on floating-point std::to_chars,
however they end up failing because calling std::format even without a
floating-point argument to format will end up requiring floating-point
std::to_chars. I believe this is an implementation artifact that could
be avoided in all cases where we know the format string at compile-time.
In the tests, I added the TODO comment only to the places where we could
do better and actually avoid relying on floating-point std::to_chars
because we know the format string at compile-time.

[TSan] Avoid deadlock between ReportRace() and dlopen() interceptor
This change prevents rare deadlocks observed for specific macOS/iOS GUI
applications which issue many `dlopen()` calls from multiple different
threads at startup and where TSan finds and reports a race during
startup. Providing a reliable test for this has been deemed infeasible.
Although I've only observed this deadlock on Apple platforms,
conceptually the cause is not confined to Apple code so the fix lives in
platform-independent code.
Deadlock scenario:
```
Thread 2 | Thread 4
ReportRace() |
Lock internal TSan mutexes |
&ctx->slot_mtx |
| dlopen() interceptor
| OnLibraryLoaded()
| MemoryMappingLayout::DumpListOfModules()
| calls dyld API, which takes internal lock
| lock() interceptor
| TSan tries to take internal mutexes again
| &ctx->slot_mtx
call into symbolizer |
MemoryMappingLayout::DumpListOfModules()
calls dyld API, which hangs on trying to take lock
```
Resulting in:
* Thread 2 has internal TSan mutex, blocked on dyld lock
* Thread 4 has dyld lock, blocked on internal TSan mutex
The fix prevents this situation by not intercepting any of the calls
originating from `MemoryMappingLayout::DumpListOfModules()`.

[mlir][tosa] Canonicalize concatenate->slice sequence
Adds a canonicalizer for the concatenate->slice sequence where
an output of slice can be replaced with an input of concatenate.
This is useful in the context of operations with complex inputs
and outputs that are legalized from a framework such as TFL.
For example, a TFL graph (FFT->FFT) will be legalized to the
following TOSA graph:
<complex input>
/ \
slice slice
\ /
FFT
/ \ -+
concatenate |
/ \ | Redundant
slice slice |
\ / -+
FFT
/ \
concatenate
|
<complex output>
Concatenate and slice operations at the boundaries of the graph are
useful as they maintain the correct correspondance of input/output
tensors to the original TFL graph. However, consecutive
complex operations will result in redundant concatenate->slice
sequences which should be removed from the final TOSA graph.
The canonicalization does not currently handle dynamic types.
