  [clang][llvm][aarch64][win] Add a clang flag and module attribute for import call optimization, and remove LLVM flag (#122831)

Switches import call optimization from being enabled by an LLVM flag to
instead using a module attribute, and creates a new Clang flag that will
set that attribute. This addresses the concern raised in the original
PR:
<https://github.com/llvm/llvm-project/pull/121516#discussion_r1911763991>

This change also only creates the Called Global info if the module
attribute is present, addressing this concern:
