717899ce - [CIR] Upstream get_bitfield operation to load bit-field members from structs (#145971)

[CIR] Upstream get_bitfield operation to load bit-field members from structs (#145971) This PR adds support for loading bit-field members from structs using the `get_bitfield` operation. It enables retrieving the address of the bitfield-packed member but does **not** yet support volatile bitfields this will be addressed in a future PR.
