  [clang] Implement CWG2627 Bit-fields and narrowing conversions (#78112)

https://cplusplus.github.io/CWG/issues/2627.html

It is no longer a narrowing conversion when converting a bit-field to a
type smaller than the field's declared type if the bit-field has a width
small enough to fit in the target type. This includes integral
promotions (`long long i : 8` promoted to `int` is no longer narrowing,
allowing `c.i <=> c.i`) and list-initialization (`int n{ c.i };`)

Also applies back to C++11 as this is a defect report.
