[COMMITTED] gccrs: session-manager: Add ast-pretty-expanded dump

[Arthur Cohen <arthur.cohen@embecosm.com>]

gcc/rust/ChangeLog:

	* rust-session-manager.cc (Session::compile_crate): Allow the dump of prettified AST
	(Session::dump_ast_pretty): New
	* rust-session-manager.h: Add new output file for pretty AST dump

Tested on x86_64-pc-linux-gnu, committed on master.
