[CIR][NFC] Resolve various nits for builtin bit operations (#148378)
This patch contains fixes for various nits mentioned in #147200: - This patch removes the `bit.` prefix in the op mnemonic. The operation names now directly correspond to the builtin function names except for `bswap` which is represented by `cir.byte_swap` for more clarity. - Since all bit operations are `SameOperandsAndResultType`, this patch updates their assembly format and avoids spelling out the operand type twice.
