feat: utilize CMake for macOS .app and .dmg creation

[shenlebantongying]

This PR encompasses various improvements:

• Makes creating .dmg or .app locally possible (by removing the need to run macdeployqt, otool, codesign after build)
• Ultimately fix, Immediate crash upon startup in macos 13.4: Namespace DYLD, Code 1 Library missing #814 and fix, Mac 12 version error report #1472
• Rename .app & .dmg so that we may submit to homebrew's cask Homebrew cask for macOS, help wanted #1141

And less important ones,

• One more step closer to removing qmake
• Remove outdated keys from .plist file
• Reduce .dmg size for by switching compression method. (macOS 10.15+)
• ...

Known issue:

The Homebrew Qt and macdeployqt's rpath bug is still not fixed, so we still have to use Qt's installer.

Known alternatives:

CMake's CPack's Drag&Drop generator is 💩💩💩. Lacks basic features and obscure to use.

So we still uses brew install create-dmg to create dmg installer.

Can any one of the known Mac users try this build? @sonerfromnurland @yshumy @homocomputeris @initial-ddl

My Mac doesn't have enough space to set up an VM to test if it works on someone else's machine.

In theory, it should work, but I am not sure.

I think my next PR would be replacing macOS's qmake builds in CI, then we can make a pre-release to check out problems and checkout the requirements for homebrew submission.

Then we submit to homebrew cask after the next formal release. @xiaoyifang

I have an Intel-based one.
