Add some perf events/data for tiered compilation (#24607)

Add some perf events/data for tiered compilation

New events:
- `Settings` - Sent when TC is enabled
  - `Flags` - Currently indicates whether QuickJit and QuickJitForLoops are enabled
- `Pause` - Sent when TC is paused (due to a new method being called for the first time)
- `Resume` - Sent when TC resumes
  - `NewMethodCount` - Number of methods called for the first time while tiering was paused
- `BackgroundJitStart` - Sent when starting to JIT methods in the background
  - `PendingMethodCount` - Number of methods currently scheduled for background JIT
- `BackgroundJitStop` - Sent when background jitting stops
  - `PendingMethodCount` - Same as above. When 0, background jitting has completed.
  - `JittedMethodCount` - Number of methods jitted in the background since the previous BackgroundJitStart event on the same thread

Miscellaneous:
- Updated method JIT events to include the optimization tier
- Added a couple more cases where tiered compilation is disabled for methods that have JIT optimization disabled for some reason
- Renamed `Duration` field of the new version of the `ContentionEnd` to `DurationNs` to indicate the units of time
- Added `OptimizationTierOptimized` to `NativeCodeVersion::OptimizationTier` to distinguish it from `OptimizationTier1`. `OptimizationTierOptimized` is now used for methods that QuickJit is disabled for, and does not send the tier 1 flag.
  - For info about the code being generated by the JIT, added info to `PrepareCodeConfig` and stored a pointer to it on the thread object for the current JIT invocation. Info is updated in `PrepareCodeConfig` and used for updating the tier on the code version and for sending the ETL event.
  - If the JIT decides to use MinOpt when `MethodDesc::IsJitOptimizationDisabled()` is false, the info is not stored. The runtime method event will reflect the JIT's choice, the rundown event will not.
- Updated to show optimization tiers in SOS similarly to PerfView
