Workaround for Ubuntu 18.04, since we still use it for the GCC 4.8 CI.
The default Rust package is 1.65 (and unlikely to change I assume?),
but the generic format parser library uses `is_some_and` which was
introduced in 1.70. So this is a simple reimplementation, directly taken
from the standard library sources.
libgrust/ChangeLog:
* libformat_parser/generic_format_parser/src/lib.rs: Add IsSomeAnd<T>
trait, impl it for Option<T>.
Compile libformat_parser and link to it.

* Make-lang.in: Compile libformat_parser.
* ast/rust-fmt.cc: New FFI definitions.

* expand/rust-macro-builtins.cc (MacroBuiltin::format_args_handler): Call
into libformat_parser.
* expand/rust-macro-builtins.h: Define format_args!() handler proper.
