https://dart-review.googlesource.com/c/sdk/+/145591 introduced a try
catch into FFI calls to call ExitHandleScope on the exception path.
However, we only need this try-catch if we actually need to exit the
handle scope on the exception path, which is not the case if we have
no handles in the signature. So this CL makes the try catch optional.
This speeds up ffi calls without handles (tested on JIT x64):
FfiCall.Uint8x01(RunTime): 206.4801280066068 us.
->
FfiCall.Uint8x01(RunTime): 203.7240782236708 us.
Also adds a test that checks that an exception can still be propagated
with Dart_PropagateError from native code when the FFI trampoline has
no try catch.

This CL introduces dart_api_dl.h which exposes a subset of dart_api.h
and dart_native_api.h for dynamic linking at runtime through the FFI.
Dynamic linking is done through including dart_api_dl.cc in a shared
library and passing NativeApi.initializeApiDLData to the init function.
This CL also includes Native API versioning to deal with possible
version skew between native api version against which native libraries
are compiled and the version in the DartVM the code is run on.
The subset of symbols in the CL includes handle related symbols, error
related symbols, handle scope symbols, and native port sumbols.

Properly running msan on this test would require us to emit
msan_unpoison and msan_poison calls in the ffi trampolines to mark
explicitly what we are doing with the stack during ffi calls.

This includes support for calling Dart_PropagateError in native code
when doing FFI calls, and catching uncaught exceptions with Dart_IsError
when doing FFI callbacks.
The support for Dart_PropagateError adds a catch entry to the FFI
trampoline, which prevents inlining these trampolines in AOT. This
regresses the FfiCall benchmarks by 1-2% in AOT.
In addition, Dart_PropagateError requires maintaining a bit whether we
entered native/VM code from generated code through FFI or not. That way
we can do the proper transition on the exception path. When entering
generated code, we store this bit on the stack, right after the entry
frame.

This prevents them from being called dynamically.
Moreover, it prevents asFunction from being called on a non-NativeFunction type argument, simplifying the amount of manual checks.
Note that this CL had to change the CFE and analzyer, and their tests (including mock_sdk) as well.
This can potentially be a breaking change, as the extension methods are only visible when `dart:ffi` is imported, while methods on objects are always visible.

Sign extension of small integers is not symmetric between register arguments and register return values.
On Linux/MacOS x64, the caller is responsible for both the arguments and return value.
Previous tests only tested equality, which tests the equality of the lowest byte. However, when printing or using the small ints arithmetic all 4 bytes are used. The new tests pass back the number in a different format.
The callback tests test the number in Dart, so they did not suffer from implicit conversions. (TestTakeMaxUint8x10 in runtime/bin/ffi_test/ffi_test_functions.cc and tests/ffi_2/function_callbacks_test.dart.)
