```
GPA: Catch invalid frees

* GPA: Catch invalid frees

Fix #14791: Catch cases where an invalid slice is passed to free().
This was silently ignored before but now logs an error. This change
uses a AutoHashMap to keep track of the sizes which seems to be an
overkill but seems like the easiest way to catch these errors.

* GPA: Add wrong alignment checks to free/resize

Implement @Inkryption's suggestion to catch free/resize with the wrong
alignment. I also changed the naming to match large allocations.
