[libpas] Add stat counter for pas_page_malloc
https://bugs.webkit.org/show_bug.cgi?id=305081
rdar://167727200
Reviewed by Keith Miller.
This new counter tracks:
1. the number of bytes mapped
2. the number of those bytes which were mapped with backing MTE memory
3. the number of those bytes which were used for small or medium pages
Notably, this does not include mmap calls used e.g. for zeroing pages,
or by clients of libpas who map their own memory before passing it in
(e.g. the JIT heap).
