  Revert "[PGO][AMDGPU] Add basic HIP offload PGO support (#177665)" (#201416)

This broke profiling builds on Windows by switching the profile library
to link against the dynamic CRT; see discussion on the PR.

There were already a number of issues reported and fixed after this PR.
Rather than piling on the fixes (and this one may need some work),
revert back to green for now to let the project recover.

This reverts commit 5db13643f4b7038db0ca304d9f8900122502935c.

Additionally, this reverts the followup PRs in
