Remove SwiftSyntaxParser module

This removes the `SwiftSyntaxParser` module, which was just a wrapper around `SwiftParser` to ease the transition for clients that previously used `SwiftSyntaxParser`. Everybody should be using `SwiftParser` by now, so remove the deprecated module.

This migrates all test cases that still provide value to other modules.

 ### XCTests
 
-The `SwiftSyntaxParser` module (the legacy parser) of this repository depends on the C++ parser library (`_InternalSwiftSyntaxParser.dylib`) to parse source code.
-The syntax node definitions of that parser library need to match those used by your SwiftSyntax checkout.
-Most of the time, the parser library included in the latest Swift Development Snapshot will fulfill this requirement.
