Subject: Refactor shader cache (#2558)

* Fix a bug in Path::find

* Fix code formatting

* Fix LockFile and add LockFileGuard

* Add PersistentCache and unit test

* Replace file path dependency list with source file dependency list

* Add note on ordering in Module/FileDependencyList

* Remove old shader cache code

* Refactor shader cache implementation

* Temporarily skip unit tests reading/writing files

* Fix warning

* Reenable lock file test

* Rename shader cache tests and disable crashing test

* Testing

* Stop using Path::getCanonical

* Fix persistent cache lock and test

* Fix threading issues

* Move adding file dependency hashes to getEntryPointHash()

* Fix handling of #include files

* Allow specifying additional search paths for gfx testing device

* Work on shader cache tests

* Update project files

* Revive shader cache graphics tests

* Split graphics pipeline test

* Fix compilation
