Create a new target type for Rust procedural macro

Rust procedural macros are special types, even though they're
technically shared libraries, they're not linked into targets and
their building follows different rules and requires different defaults
(e.g. they don't support sanitizers unlike other Rust targets). This
change introduces new rust_proc_macro target type that could be used for
building procedural macros rather than overloading shared_library.
