YJIT: Add codegen for Integer methods

[k0kubun]

Similar to #7645, this PR adds codegen to skip pushing a frame like equivalent opt_* insns for Integer#*, Integer#/, and Integer#[], which I found useful for optimizing Optcarrot while working on RJIT.

They don't seem to have a significant impact on headline benchmarks, but Integer#* and Integer#/ could be used by actual applications.
