Rollup merge of #55767 - tromey:disable-some-pretty-printers, r=alexcrichton

Disable some pretty-printers when gdb is rust-enabled

A rust-enabled gdb already knows how to display string slices,
structs, tuples, and enums (and after #54004, the pretty-printers
can't handle enums at all).  This patch disables these pretty-printers
when gdb is rust-enabled.

The "gdb-pretty-struct-and-enums-pre-gdb-7-7.rs" test is renamed,
because it does not seem to depend on any behavior of that version of
gdb, and because gdb 7.7 is 4 years old now.
