hle: Improve safety (#2778)
* timezone: Make timezone implementation safe

* hle: Do not use TrimEnd to parse ASCII strings

This adds an util that handle reading an ASCII string in a safe way.
Previously it was possible to read malformed data that could cause
various undefined behaviours in multiple services.

* hid: Remove an useless unsafe modifier on keyboard update

* Address gdkchan's comment
