Coalesce adjacent free blocks during `page_free_array()` in
`core/storage/btree`.
Instead of immediately passing free cells to `free_cell_range()`, buffer
up to 10 free cells and try to merge adjacent free blocks. Break on the
first merge to avoid time complexity, `free_cell_range()` coalesces
blocks afterwards anyways. This follows SQLite's [`pageFreeArray()`](htt

Removed this TODO:

// TODO: implement fancy smart free block coalescing procedure instead of dumb free to
