Refactor getclassvariable (#5137)
* Refactor getclassvariable
We only need the cref when we have a cache miss so don't look it up until we
need it. This speeds up class variable reads in the interpreter but
also simplifies the jit code.
Benchmarks for master vs this branch (without yjit):
Before:
```
Warming up --------------------------------------
read a cvar 1.276M i/100ms
Calculating -------------------------------------
read a cvar 12.596M (± 1.7%) i/s - 63.781M in 5.064902s
```
After:
```
Warming up --------------------------------------
read a cvar 1.336M i/100ms
Calculating -------------------------------------
read a cvar 13.114M (± 3.6%) i/s - 65.488M in 5.000584s

* Clean up function signatures / remove dead code
rb_vm_getclassvariable signature has changed and we don't need
rb_vm_get_cref.
