Fix fast tail calls on Windows ARM64. (#37192)

LowerFastTailCall has code that looks for incoming stack arguments
that may be overwritten by outgoing stack arguments and copies
them to a temp. The logic was incorrect for Windows Arm64 because it was
assuming shadow space, which only exists in Windows x64 abi.

Fixes #31729.
Fixes #36911.
