* Fixes after rebase

* Fix embed.cpp compilation

Fix implicit conversion from int when using QString.arg(...)

* Fix Qt6 signature change for nativeEventFilter (#7254)

* win32EventFilter is currently used to intercept top-level Window events (currently, to avoid VSTs setting transparency of the parent application)

* fix broken signal slot connections (#7274)

QComboBox activated() replaced with textActivated() since Qt 5.14

* Enabled VSTs on Qt 6 (#7273)

* enabled VST support for Qt 6 builds
* Note : Embedding on QT6 will be buggy on linux as a result of using qt embedding, which unfortunately is a qt bug which hasn't been resolved.

* Added lines in between bars
* Changed bar lines to follow snap size

* Fix bad merge

* Fixes after rebase

* Simplify QTX_WRAP_CPP call

* Remove comments that are obvious to a developer

* Whitespace

* Try using Qt 6 for MSVC CI

I chose Qt 6.5 because it's the last Qt LTS release with declared
support for Visual Studio 2019. Once we upgrade to Visual Studio 2022,
we could upgrade Qt as well.

Also fixes two memory leaks in MidiWinMM

* Fix GuiApplication on MSVC

* Fix interpolateInRgb

* Try building with patched Calf

* Fix submodule

* Fix OpulenZ build

* Try to fix zyn

* Fix comment

* Ty to fix zyn (again)

* Ty to fix RemotePluginBase

* Revert "Ty to fix RemotePluginBase"

This reverts commit 92dac44ffb11e19d1d5a21d9155369f017bd59e9.

* Update plugins/ZynAddSubFx/CMakeLists.txt

Some comparisons were using ">" rather than ">="

The Qt bug that used to be present appears to have been fixed, so the
workaround can be removed
