  Log Message:
  -----------
  [CIR] Implement isMemcpyEquivalentSpecialMember for trivial copy/move ctors (#186700)

Implements isMemcpyEquivalentSpecialMember in CIR codegen so that
trivial copy/move constructors and defaulted union copy/move ops emit a
cir.copy directly instead of making a real constructor call. The logic
is shared with OG codegen by moving the implementation into ASTContext,
where it also gains the pointer field protection (PFP) check that was
previously missing in CIR.
