libiberty: Support the new ("v0") mangling scheme in rust-demangle
This is the libiberty (mainly for binutils/gdb) counterpart of
https://github.com/alexcrichton/rustc-demangle/pull/23.
Relevant links for the new Rust mangling scheme (aka "v0"):
* Rust RFC: https://github.com/rust-lang/rfcs/pull/2603
* tracking issue: https://github.com/rust-lang/rust/issues/60705
* implementation: https://github.com/rust-lang/rust/pull/57967
This implementation includes full support for UTF-8 identifiers
via punycode, so I've included a testcase for that as well.

* rust-demangle.c (struct rust_demangler): Add
skipping_printing and bound_lifetime_depth fields.
(eat): Add (v0-only).

(struct rust_mangled_ident): Add punycode{,_len} fields.
(parse_ident): Support v0 identifiers.
(print_str): Respect skipping_printing.
