Revert "[fastcall] Implement support for TypedArray arguments"

This reverts commit 84d5b027.

Reason for revert: Breaks UBSan - https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20UBSan/17349/overview

Original change's description:
> [fastcall] Implement support for TypedArray arguments
>
> This CL adds TypedArrays as supported arguments for fast API calls.
> It implements "exact type" matching, i.e. if Float32Array is expected
> and e.g. Int32Array is passed instead, the generated code bails to the
> slow callback.
>
