YJIT: Implement new struct accessors (#5161)

* YJIT: Implement optimized_method_struct_aref

* YJIT: Implement struct_aref without method call

Struct member reads can be compiled directly into a memory read (with
either one or two levels of indirection).

* YJIT: Implement optimized struct aset

* YJIT: Update tests for struct access

* YJIT: Add counters for remaining optimized methods

* Check for INT32_MAX overflow

It only takes a struct with 0x7fffffff/8+1 members. Also add some
cheap compile time checks.

* Add tests for non-embedded struct aref/aset
