Compute the size of pages before allocating memory (#14650)

Browse source 
`start_memory_manager()` calls `zend_mm_init()` via `alloc_globals_ctor()`
before setting `REAL_PAGE_SIZE` to the right value. Moving the `REAL_PAGE_SIZE`
setting block before the call to `alloc_globals_ctor()` makes the allocator
behave properly on systems with a page size different than 4k.
