Addresses #1567
Created a AST node InlineAsm similar to the one found in rustc.
As there is no Symbol struct/class in gccrs I have made every instance
of Symbol a string.
gcc/rust/ChangeLog:
* ast/rust-ast-full-decls.h (class InlineAsm):Added class declaration.
* ast/rust-expr.h (class InlineAsm):Added class definition.
