Subject: Test for serializing out and reading back Stdlib (#1605)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Mangling/module name extraction for GenericDecl

* Add comment on SerialFilter to explain re-enabling Stmt.

* Support setting up SyntaxDecl when reconstructed after deserialization.

* Improvements to setup SyntaxDecl.

* Fix typo so can read compressed SourceLocs.

* Fix issue with SourceManger.

* Simple test for serializing out stdlib and reading back in.

* Fix calling convention.

* Add override to StdLib impls.

* Fix typo.

* Apply testing to an actual compute test when using load-stdlib
Make -load/compile-stdlib processable by Slang
Move out testing into util into TestToolUtil so can be shared.

* Slightly more concise setup of session.

* Fix some errors introduced with session handling.

* Made setup for compile same across slangc and slangc-tool.
