Add project settings for default importers

[mlm-games]

Closes godotengine/godot-proposals#12770.
Closes #108512

Doesn't import older files by default to maintain .import settings, could use the tools -> upgrade project files for that

Toggling it on and adding a svg file would import it as a SVGTexture else as a CompressedTexture2D

Production edit: Closes godotengine/godot-proposals#2500

Only the mono linux editor says documentation is incomplete? Is it just a pipline problem because others don't seem cancelled..

Some runners only test the build process, some do unit tests, and some do additional stuff like documentation checks. I think only the Linux Editor w/ Mono target checks the documentation.

Edit: My guess is, your GLOBAL_DEF is called in the wrong location. The docs seem to complain that your added setting does not exist, so it's not registered at the time it's checking.

Thanks for the ref, moved it to ProjectSettings (and removed some unneeded flags i used looking at others there, hadn't put it there initially because the filesystem/import settings were not present initially)

Moved the setting doc lower according to linter

Note that there's a more generalized proposal requesting this for any format, not just SVG:

• Allow defining what importer to use for a given file extension godot-proposals#2500

There's a salvageable PR implementing it:

• Allow defining default importers per file extension #72848

Have tried experimenting with it and can't seem to find a good ui position. It does work (changing a setting, for eg. svg, and adding a svg file causes it to be imported as svgtexture, haven't tested it for other file formats though)

[mlm-games]

FPushed the changes (changed the names of some due to it being confusing while handling importer-settings (named as settings initially) and default-importer-settings)

[mlm-games]

Made the changes (don't mind the tab names)

"Importer Defaults" tab should be first like before IMO.
Also "Default Importers" could be called "Extension Importers" or "Extension Defaults".

Please use the batch commit function for suggestions in the future, to avoid noisy updates and a lot of extra runs of CI (you are a first time contributor right now so it doesn't clutter the runner, but later it would)

Um not sure where the function is, but will try to just make the changes locally in the editor and push all directly instead (from next time)

It's the button that says "add suggestion to batch"

Oh... probably didn't notice it 😅

[mlm-games]

Made all the changes (hopefully), and renamed the tab to "Extension Defaults".

Added the missing ones
