Logging API change (refactor) (#19324) 
* Rename LogType to Log

* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.

* Mac/ARM64 buildfix

* Do the same with the hle result log macros

* Rename the log names to mixed case while at it.

* iOS buildfix

* Qt buildfix attempt, ARM32 buildfix
