Merge raw_bitcast and bitcast (#5175)

- Allow bitcast for vectors with differing lane widths - Remove raw_bitcast IR instruction - Change all users of raw_bitcast to bitcast - Implement support for no-op bitcast cases across backends This implements the second step of the plan outlined here: https://github.com/bytecodealliance/wasmtime/issues/4566#issuecomment-1234819394
