Utilisation of get_page_from_raw() in pageinspect

Hi All,

Currently, get_page_from_raw() is not used in the pageinspect
functions for btree and heap to fetch a page image from raw page.
However, the pageinspect for gin and hash is using it to avoid server
crash on alignment picky machines with MAXALIGN = 8. Shouldn't we
start using it in the pageinspect functions for btree and heap as well
for safety purpose. Thoughts?
