* Add a C++ demangler for PrintStackTrace
This is a simple C++ demangler (only supporting name demangling) that will
probably be enough for any stacktrace cases.
* Create Ryujinx.Core.OsHle.Diagnostics.Demangler and move DemangleName
* Rename Demangler -> Demangle + Fix coding style
* Starting a real parsing for demangler (still simple and no compression support yet)
* Partially implement decompression
* Improve compression support (still need to fix errored compression indexing)
* Some cleanup
* Fix Demangle.Parse call in PrintStackTrace
* Trim parameters result to get more clear prototypes
* Rename Demangle -> Demangler and fix access level
* Fix substitution possible issues also improve code readability
* Redo compression indexing to be more accurate
* Add support of not nested function name
* Add ISystemDisplayService::GetDisplayMode & IManagerDisplayService::SetLayerVisibility
Also add some missing PrintStub calls
* Fix import ordering & Fix incorrect value for the third word in GetDisplayMode
