[mono][jit] Disable passing SIMD args in SIMD regs on arm64. (#87540)

It has the following problems:
- the gshared versions of SIMD types like Vector<T_INT> are not marked
  as SIMD, so there is a calling convention mismatch if the callee is
  generic shared.
- the gsharedvt code doesn't support it, i.e. it asserts in get_arg_slots ().
- the dyncall code might not support it either.

Fixes https://github.com/dotnet/runtime/issues/87277.
