Delete _InternalSwiftSyntaxParser And Its Build Infrastructure

This is the start of the removal of the C++ implementation of libSyntax in favor of the new Swift Parser and Swift Syntax libraries. Now that the Swift Parser has switched the SwiftSyntaxParser library over to being a thin wrapper around the Swift Parser, there is no longer any reason we need to retain any libSyntax infrastructure in the swift compiler. As a first step, delete the infrastructure that builds lib_InternalSwiftSyntaxParser and convert any scripts that mention it to instead mention the static mirror libraries. The --swiftsyntax build-script flag has been retained and will now just execute the SwiftSyntax and Swift Parser builds with the just-built tools.
