fix(gui): allow to select file on mapping export

* Add option to export mappings as Tiny v2 file

* Comply with JADX's import order conventions

* Only use Java 8 features

* Only use Java 8 features (2)

* Export comments to mappings file

* Method args test (doesn't work)

* Make method arg mapping exports work now

* Use `getTopParentClass()` instead of `getParentClass()`

See https://github.com/skylot/jadx/pull/1505#issuecomment-1145064865

* Remove unneeded method load call

* Small code cleanup; initial (broken) support for method vars

* Fixes regarding inner classes

* Add option to export mappings as Enigma directory

* Add option to export mappings as Enigma file/directory

Temporarily move to my mapping-io fork until this PR gets merged: https://github.com/FabricMC/mapping-io/pull/19

* Fix method vars' lv-indices

* Use correct offset value for method var mappings

* Also supply lvt-index for method var mappings

* Clarify why we're using local mapping-io fork; comment out Fabric Maven for now

* Remove unnecessary `public` modifier

* Make an `if` condition less complicated

* Move mapping export code into jadx-gui (for now)

* Make mapping export async; make export menu only clickable when everything is loaded

* Fix export mappings menu field declaration position
