MDEV-8139: Clean up the freeing of B-tree pages

Browse source 
btr_page_free(): Renamed from btr_page_free_low().
If scrubbing is enabled, zero out the page with proper redo logging.
Only pass ahi=true to fseg_free_page() if the page is actually indexed.

fil_space_t::modify_check(): Renamed from fsp_space_modify_check().

fsp_init_file_page(): Define inline.
