Allow per constructor refinement of distinct-constructor-tables
Introduce `-fno-distinct-constructor-tables`. A distinct constructor table
configuration is built from the combination of flags given, in order. For
example, to create distinct constructor tables for all constructors except for a
specific few named `C1`,..., `CN`, pass `-fdistinct-contructor-tables` followed
by `fno-distinct-constructor-tables=C1,...,CN`. To only generate distinct
constuctor tables for a few specific constructors and no others, just pass
`-fdistinct-constructor-tables=C1,...,CN`.
The various configuations of these flags is included in the dynflags
fingerprints, which should result in the expected recompilation logic.
Adds a test that checks for distinct tables for various given or omitted
constructors.
Fixes #23703
