  [LibC] Refactor arm64 to aarch64 for darwin. (#141509)

Fixes [#141505](https://github.com/llvm/llvm-project/issues/141505)

The main intention behind this PR is to update the
LibCTargetArchitecture for arm64 to use the implementation of aarch64
architecture and not arm32.

This is a historical issue , and is a blocker to issue #138407. 

The intended fix is to set the `LibCTargetArchitecture` to aarch64 when
it matches arm64 , this in turn would help us run darwin/aarch64
specific code on our MacOs pipeline in the git actions.

Methods used to search and find "darwin/arm" directories was  

1. "find . -type d -path "*/libc/*/darwin/arm" in a linux terminal to
check for arm specifically
2. "find . -type d -path "*/libc/*/darwin/*" to ensure there are no
directories that are named "*arm*" where star is a wildcard for any
character.
