Ulan Degenbaev 5bc1d29105 [heap] Make assert in Page::ShrinkToHighWaterMark more robust. 
Currently Page::ShrinkToHighWaterMark checks that there is only one
filler in the to-be-freed area at the end of the page. This does not
hold if an allocation observer is active.

We should instead check that the to-be-freed area does not contain
allocated objects and will not contain allocated objects:
1) Following chain of fillers we arrive at the end of the page.
2) The free list of the page is empty.

This patch also changes PagedSpace::ResetFreeList to evict free list
entries of each page, instead of just reseting the global free list.

It also removes invalidation of free list categories.
Now FreeList::EvictFreeListItems simply evicts free list entries without
invalidating free list categories.
