   [DebugInfo] Change handling of structured bindings of bitfields (#94632)

Currently we use DW_OP_plus_uconst to handle the bitfield offset and
handle the bitfield size by choosing a type size that matches, but this
doesn't work if either offset or size aren't byte-aligned. Extracting
the bits using DW_OP_LLVM_extract_bits means we can handle any kind of
offset or size.
