Replace stdlib on Slang API with CoreModule (#5405)

This is a breaking change in a way that the Slang API function names are changed. All of them are commented as "experimental" and we wouldn't provide a back-ward compatibility for them.

Following functions are renamed:

compileStdLib() -> compileCoreModule()
loadStdLib() -> loadCoreModule()
saveStdLib() -> saveCoreModule()
slang_createGlobalSessionWithoutStdLib() -> slang_createGlobalSessionWithoutCoreModule()
slang_getEmbeddedStdLib() -> slang_getEmbeddedCoreModule()
hasDeferredStdLib() -> hasDeferredCoreModule()
Following command-line arguments are renamed:

"-load-stdlib" -> "-load-core-module"
"-save-stdlib" -> "-save-core-module"
"-save-stdlib-bin-source" -> "-save-core-module-bin-source"
"-compile-stdlib" -> "-compile-core-module"
