Added compiler-core project (#1775)

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

* Split out compiler-core initially with just slang-source-loc.cpp

* More lexer, name, token to compiler-core.

* Split Lexer and Core diagnostics.

* Move slang-file-system to core.

* Add slang-file-system to core.

* More DownstreamCompiler into compiler-core

* Fix typo.

* Add compiler-core to bootstrap proj.

* Small fixes to premake

* For linux try with compiler-core

* Remove compiler-core from examples.

* Added NameConventionUtil to compiler-core

* Add global function to CharUtil to *hopefully* avoid linking issue.

* Hack to make linkage of CharUtil work on linux.
