This moves `libstdcxx.modulemap` and `libstdcxx.h` from `*.xctoolchain/usr/lib/swift/macosx/arm64e` to `*.xctoolchain/usr/lib/swift/macosx` to simplify distribution. rdar://110788977 (cherry picked from commit 3e28a7c)

Explanation: This moves
libstdcxx.modulemapandlibstdcxx.hfrom*.xctoolchain/usr/lib/swift/linux/x86_64to*.xctoolchain/usr/lib/swift/linuxto simplify distribution.Scope: This simplifies the CMake build scripts to ignore the architecture for these headers, and adjusts the compiler logic used to discover the headers.
Risk: Medium, this alters the distribution of the toolchain headers on Linux.
