YJIT code pages refactoring for code GC (#5073)

Browse source 
* New code page allocation logic

* Fix leaked globals

* Fix leaked symbols, yjit asm tests

* Make COUNTED_EXIT take a jit argument, so we can eliminate global ocb

* Remove extra whitespace

* Change block start_pos/end_pos to be pointers instead of uint32_t

* Change branch end_pos and start_pos to end_addr, start_addr
