Configured the garbage collector for lower spikes (#88)

Did you know that the garbage collector's default settings are designed for single-threaded applications and quick start-up times? We don't care about either of these.

Configured:
- Concurrent GC (default is true) (set for clarity)
- RetainVM: segments that should be deleted are put on a standby list for future use (default is false)
- QuickJit: enabling quick JIT decreases startup time but can produce code with degraded performance characteristics; for example, the code may use more stack space, allocate more memory, and run slower. (default is true) (disabled)
- ReadyToRun: configures whether the .NET runtime uses pre-compiled code for images with available ReadyToRun data; disabling this option forces the runtime to JIT-compile framework code. (default is true) (set to false, we dont publish with this option anyway)
- TieredPGO: this setting enables dynamic (tiered) profile-guided optimization (PGO) in .NET 6 and later versions. If quick JIT is disabled but tiered compilation is enabled, only pre-compiled code participates in tiered compilation. If a method is not pre-compiled with ReadyToRun, the JIT behavior is the same as if tiered compilation were disabled.

Features:
- Set ``GCLatencyMode.Interactive`` when in-menu and emulator is paused, otherwise uses ``GCLatencyMode.LowLatency``.
- Added a new UI option in the Settings > CPU menu to toggle ``GCLatencyMode.LowLatency`` during guest runtime.
