Dalton Messmer 18252088ba Refactor Effect processing (#7484)
* Move common effect processing code to wrapper method

- Introduce `processImpl` and `sleepImpl` methods, and adapt each effect
plugin to use them
- Use double for RMS out sum in Compressor and LOMM
- Run `checkGate` for GranularPitchShifterEffect
- Minor changes to LadspaEffect
- Remove dynamic allocations and VLAs from VstEffect's process method
- Some minor style/formatting fixes

* Fix VstEffect regression

* GranularPitchShifterEffect should not call `checkGate`

* Apply suggestions from code review

Co-authored-by: saker <sakertooth@gmail.com>

* Follow naming convention for local variables

* Add `MAXIMUM_BUFFER_SIZE` and use it in VstEffect

* Revert "GranularPitchShifterEffect should not call `checkGate`"

This reverts commit 67526f0ffe.

* VstEffect: Simplify setting "Don't Run" state

* Rename `sleepImpl` to `processBypassedImpl`

* Use `MAXIMUM_BUFFER_SIZE` in SetupDialog

* Pass `outSum` as out parameter; Fix LadspaEffect mutex

* Move outSum calculations to wrapper method

* Fix Linux build

* Oops

* Apply suggestions from code review
