  [PatternMatch] Add a matching helper `m_ElementWiseBitCast`. NFC. (#80764)

This patch introduces a matching helper `m_ElementWiseBitCast`, which is
used for matching element-wise int <-> fp casts.
The motivation of this patch is to avoid duplicating checks in
https://github.com/llvm/llvm-project/pull/80740 and
https://github.com/llvm/llvm-project/pull/80414.
