Revert "Toggle DisableFrameThrottling setting by clicking on FPS"

Browse Source 
This commit reverts PR #2037. Passing `NativeSettings` to emulation code through a member reference, instead of a local variable, caused unpredictable crashes when using custom GPU drivers (v615+) on some Qualcomm SoCs.
The exact cause of the issue remains unknown, my best guess is that it was caused by an incorrect optimization performed on the Kotlin bytecode in release mode, which caused an issue when reading memory that had been forked, because of running emulation in a separate process.
Runtime settings modification will be reimplemented in the future via an alternative method.
