Support embed component path

[taichi-ishitani]

close #1751

Scoped identifiers wrapped with \((( and ))) in embed blocks are resolved and the results are emitted into the code blocks.

Example:

Veryl

module Module47C {
    inst u_a: Module47A;

    embed (inline) sv{{{
        bind u_a
        \(((Module47B))) u_b ();

        initial begin
            $display("hello");
        end
    }}}
}

Generated SV

module veryl_testcase_Module47C;
    veryl_testcase_Module47A u_a ();

    `ifndef SYNTHESIS
        bind u_a
        veryl_testcase_Module47B u_b ();

        initial begin
            $display("hello");
        end
    `endif
endmodule

Updating parol v4 is required to implement this feature.
