  [CIR] Add initial support for bitfields in structs (#142041)

This change adds support for bitfields CIR records can now contain bit
fields.

I’ve updated the `CIRGenBitFieldInfo` comment, which originally came
from the incubator and was identical to the one in OGCodeGen, to better
reflect the current implementation.

Support for bitfields in unions big-endian architectures and `get` and
`set` operations remains unimplemented and will be addressed in a future
patch.
