mm: replace __GFP_NO_CODETAG with ALLOC_NO_CODETAG

Now that alloc_pages has an entrypoint that allows passing alloc_flags, we
can take advantage of this to start removing GFP flags that are only used
for mm-internal stuff.

This requires also plumbing the alloc_flags into some more of the
allocator code, in particular __alloc_pages[_noprof]() gets an alloc_flags
arg to go along with its callees, and we now need to pass those flags
deeper into the allocator so they can reach the alloc_tag code.

While moving the flag definition into page_alloc.h, also update the
comment per Hao's suggestion.

No functional change intended.
