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 checks whether export/android/android_sdk_path in the Editor Settings is valid.
  • If not, it prompts the user to download and set up the Android SDK.
  • If the user accepts, AndroidSDKManager downloads and uses the Android CLI to query, set up and update the Android SDK packages used by the Godot editor.
  • The install is done in a location specific to the Godot editor, and export/android/android_sdk_path is updated once the set up is complete with the new location.
• Java SDK setup:
  • AndroidSDKManager checks for the presence of a valid Java SDK at the path specified by export/android/java_sdk_path in the Editor Settings.
  • If the install is invalid or missing, it prompts the user to download and set up the Java SDK.
  • If the user accepts, AndroidSDKManager downloads and sets up a version of the Java SDK from https://adoptium.net/.
  • The install is done in a location specific to the Godot editor, and export/android/java_sdk_path is updated once the set up is complete with the new location.

The feature is can be accessed from two locations:

• It shows in the Export Presets window when an Android preset is added, and the editor detects that the Android / Java SDK is not valid.

• The Install Android Build Template... in the Project menu was renamed to Setup Android Build.... The updated button triggers the prompt for installing the Android / Java SDK when it detects they are not properly set up.

Advanced users still have the ability to set up and configure the Android and/or Java SDK on their own if desired.

Remaining TODOs:

• Testing and validation on Windows
• Testing and validation on Linux
• Testing and validation on MacOS
• Check for online access prior to downloading SDKs

The feature is made available in the Export Template Manager via the addition of a new Setup Android SDK button.

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).

@m4gr3d I think, it might be better to place this button directly in Android preset. Thought?

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.

Fixed the issue on Windows, and validated the feature works as expected.

The class should be called AndroidSDKManager rather than AndroidSdkManager to be consistent with existing classes such as HTTPRequest or WebRTCDataChannel.

Feedback from discussions with @dsnopek and @syntaxerror247:

• Rename Install Android Build Template... to Setup Android Build
• Update the button logic to check for the Android SDK, and prompt the user for install if it's not already installed.
• Move the Setup Android SDK button in Automate Android & Java SDK setup #121849 from the Export Template Manager to the Export Window. It should be surfaced as a link similar to what we do for the Manage External template link

Needs a rebase

Suggested change

	if (!AndroidSDKManager::is_java_sdk_setup()) {
	setup_android_java_sdk->set_text(TTRC("Setup Java SDK"));
	if (!AndroidSDKManager::is_java_sdk_setup() && !AndroidSDKManager::is_android_sdk_setup()) {
	setup_android_java_sdk->set_text(TTRC("Setup Android Build"));
	} else if (!AndroidSDKManager::is_java_sdk_setup()) {
	setup_android_java_sdk->set_text(TTRC("Setup Java SDK"));

Are you suggesting to change the label when both SDKs are not set up? I'm not sure I see what difference that would make.

[syntaxerror247]

When both is missing it only says Setup Java SDK which looked a bit odd to me. When pressed, dialog will also later popup to setup Android SDK, so it seemed correct to say Setup Android Build in this case. It's not a big deal anyways, so proceed as you like.

Looks good and works as expected (tested on Linux). This is a really great improvement to the Android build setup!
