Maya Lekova a6da816119 Reland^2 "[fastcall] Enable float support on arm64 simulator""
This is a reland of d7c3f1cd8a. It fixes
a build failure on native arm64.

Original change's description:
> Reland "[fastcall] Enable float support on arm64 simulator"
>
> This is a reland of b9ddcbc86f
>
> The original CL was reverted due to an MSAN issue, that is fixed by
> moving the signature mapping onto the Isolate (instead of having
> per-thread storage, which got invalid on multithreaded compilation).
>
> This CL also contains fixes for the Bazel config and for a data race
> when obtaining the PerIsolateSimulatorData.
>
> Original change's description:
> > [fastcall] Enable float support on arm64 simulator
> >
> > This CL adds support for handling calls to C functions with arbitrary
> > signatures on the arm64 simulator. It adds infrastructure for
> > encoding the signature data from CallDescriptor and FunctionInfo
> > classes into a compact representation, stored in the simulator and
> > called EncodedCSignature.
