Automate Android & Java SDK setup

[m4gr3d]

What problem(s) does this PR solve?

This PR introduces the AndroidSdkManager class which is used to automate the download, setup and management of the Android and Java SDK in the Godot editor.

• Android SDK setup: AndroidSdkManager downloads and uses the Android CLI to query, set up and update the Android SDK packages used by the Godot editor.
• Java SDK setup: AndroidSdkManager checks for the presence of a valid Java SDK at the path specified in the Editor Settings, and if missing, it downloads and sets up a version of the Java SDK from https://adoptium.net/.

The feature is made available in the Export Template Manager via the addition of a new Setup Android SDK button.
Advanced users still have the ability to set up and configure the Android and/or Java SDK on their own if desired.

The feature was tested on MacOs.

Remaining TODOs:

• Testing and validation on Windows
• Testing and validation on Linux

This doesn't seems like the right place for this button.
@m4gr3d I think, it might be better to place this button directly in Android preset. Thought?

Or, we can also go with the approach we had discussed:

1. Update this menu option to "Setup Android Build Environment"

2. And update this dialog to also have a button "Setup Andorid SDK" (if it's not already installed).

Both the Install Android build template button and the export presets are project specific, whereas the Java and Android SDK are editor-wide setups. For that reason, the primary access needs to leave alongside other editor-wide settings / buttons / features.
The export preset window does surface the Manage Export Templates button when the Android / Java SDKs are not properly set up, which opens the 'Export Template Manager' allowing the user to complete the setup.

Suggestions for other locations are welcomed though. And I welcome input from the @godotengine/usability team.

I'm running into errors extracting the Java SDK when testing on Windows.. Will dig into the issue tomorrow.

Should we be updating to version 36 of the build tools and platform?
