Subject: Building with embedded stdlib (#1634)

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

* Move reflection to reflection-api.

* Slight reorg to pull out potentially Slang internal functions from the reflection API impls.

* Remove visual studio projects

* Fix for slang-binaries copy.

* Add the visual studio projects in build/visual-studio

* Remove miniz project.

* Differentiate the linePath from the filePath.

* Improve comment in premake5.lua + to kick of CI.

* Kick CI.

* Use COM compile request for calls to functions inside api-less-slang.
Add static-slang project.

* Fix const typo issue.

* Don't include 'core' link in 'api-less-slang'

* Removed static-slang lib causes problems on linux with linking.
Embed Slang stdlib
Added StaticBlob
Added dumpSourceBytes
Use ConstArrayView for the archive.
At startup allow loading of zip with stdlib.
Made -save-stdlib -load-stdlib take a name
Added '-save-stdlib-bin-source' to save out serialized stdlib as source.

* Ability enable/disable stdlib embedding.

* Fix problem with moduleDecl not having module pointer set when serialized in.

* Set of debugdir for slang-test and examples.

* Add slang-stdlib-api.cpp

* Update slang filters for VS.

* Try to use pic, and -mcmodel=medium

* Some more efforts ot make premake work.

* WIP premake5.lua from previously working version.

* Remove api-less-slang project.

* Disable dllexport on gcc/clang.

* Embed via slangc-bootstrap.

* Fix slang-profile. Always compiles without stdlib.

* Use pic "On"

* Remove slangc-bootstrap and embed-stdlib-generator if embedding not required. Make bootstrap run the generators.

* Improve comments in premake5.lua.
Kick off another CI build.

* Remove generation of stdlib source from std-lib-serialize.slang
