Revert "[fastcall] Enable float support on arm64 simulator"

Browse Source 
This reverts commit b9ddcbc86f.

Reason for revert: Hits unreachable on MSAN, see https://bugs.chromium.org/p/chromium/issues/detail?id=1267854

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.
>
> Design doc:
> https://docs.google.com/document/d/1ZxOF3GSyNmtU0C0YJvrsydPJj35W_tTJZymeXwfDxoI/edit
>
> This CL is a follow up on the native support added in
> https://chromium-review.googlesource.com/c/v8/v8/+/3182232
> and is partially based on the previous attempt:
> https://chromium-review.googlesource.com/c/v8/v8/+/2343072
>
