Improved Logger (#1292)
* Logger class changes only

Now compile-time checking is possible with the help of Nullable Value
types.

* Misc formatting

* Manual optimizations

PrintGuestLog
PrintGuestStackTrace
Surfaceflinger DequeueBuffer

* Reduce SendVibrationXX log level to Debug

* Add Notice log level

This level is always enabled and used to print system info, etc...
Also, rewrite LogColor to switch expression as colors are static

* Unify unhandled exception event handlers

* Print enabled LogLevels during init

* Re-add App Exit disposes in proper order

nit: switch case spacing

* Revert PrintGuestStackTrace to Info logs due to #1407

PrintGuestStackTrace is now called in some critical error handlers
so revert to old behavior as KThread isn't part of Guest.

* Batch replace Logger statements
