Subject: `Repro` functionality (#1085)

* WIP on serialize/save state.

* Relative string encoding.

* Added RelativeContainer unit test.
Split out RelativeContainer into core.

* Fix bug in RelativeString encoding.

* More work around relative container.

* Fix checks.

* Use RelativeBase for safe access.
Use malloc/free/realloc instead of List.

* Add natvis support for relative types.

* Setting up of state (not includes) writing of repro state.

* Capture after spCompile.

* Writing SourceFile and file system files.
Added -dump-repo

* First pass at loading state.

* First pass at reading repro.

* Small optimization around Safe32Ptr

* Refactor how repro data is stored - to make saving off the files more simple, by having all all backed by 'files'.
Make file loading always set up PathInfo so we get uniqueIdentifier info.

* Generate unique file names.

* Added RelativeFileSystem
Added saveFile to ISlangFileSystemExt and implemented for interfaces
Added mechanism to save of files (and manifest)

* Added ability to replace files in repo with directory holding their contents.

* Add support for entry points.

* Fix problem compiling on linux.

* Added SIMPLE_EX option, where everything on command line must be specified.

* Fix typo in unit test for relative container.

* Fix another typo in unit test for RelativeContainer.

* Fix small bugs.

* Fix release unused variable issue in slang-state-serialize.cpp

* Fix checking for SIMPLE_EX in testing, else broke COMMAND_LINE_SIMPLE.

* Fix warnings on 32 bit debug build.

* Added import-subdir-search-path-repro.slang test. Although disabled for now as writes to root of slang project.

* Remove wrong version of import-subdir-search-path-repro.slang

* Added import-subdir-search-path-repro.slang
