Migrate Project Gen to Skate

[linhpha]

This PR moves Project Gen Compose app to Skate so it can be called directly from the IDE. I made some modifications, including:

• Add a new ProjectGenWindow that extends DialogWrapper to wrap around the Compose app
• Create projectgenlock on the fly and delete it when dialog is dismissed
• Add an Alert dialog on file path errors
• Grab the DarkMode status from the IDE Theme using JBColors.isBright
• Make the Quit button to exit the dialog. It was exiting the application before
• Remove the old TerminalWrapper code

Remaining work I haven't been able to port over. Running into some issues that might take more time

• Updating the Font to Lato
• Adding the icon of the app

Test:
Light mode

light_mode_project_gen.mov

Dark mode

project_gen.mov

Re: the remaining work

I think we should actually try using the jetbrains/jewel compose theme instead to make this look native in the IDE rather than material. No need to add custom fonts or bring our own icon. Can be a follow up though!

Another thought: can we change the done dialog and do something like a "Close and sync" + "Close", with the former being the primary?

We may also need the kotlin.multiplatform plugin here in place of kotlin.jvm but not sure

[linhpha]

I was thinking since Skate is Intellij plugin, having kotlin.jvm should be enough. Does having kotlin.multiplatform mean we'll extend to other platforms like iOS?

[ZacSweers]

Not necessarily, it just sets up the KMP structure. If you look at the build file in the original repo, it does the same thing.

[linhpha]

ah I see. I can try moving the KMP structure over
