Create strings.xml files for project name translations

[amanj120]

When a Godot game is being exported, one of the processes that takes place is that the resource table is modified to have different translations of the project name. This PR accomplishes the same purpose by writing strings.xml files in the Gradle project directory.

Note: This PR builds off of #39864, the store_string_at_path method will be provided through that PR.

For more details on the final scope of this project, read this comment.

The _create_project_name_strings_files method isn't currently called anywhere in the code, but it will be useful in subsequent PR's.

We are working on this PR with @m4gr3d, as explained here

The approach used here has visibility issues.

Unless a contributor is familiar with the added logic here, she/he may inadvertently create a string resource file in the project and be confused when the end result is not as expected since this logic would overwrite that file.

Even when a contributor is familiar with this logic, the addition of new string values now becomes a cumbersome task.

What about the approach of having the string resources already in the gradle project (e.g: moving them from the lib to the app module) and just overwriting the target string value?

I'm replying to this to indicate that we've resolved this issue.

Changes look good overall, though I have the same nitpicks on some of the xml files as in #40260.

Can you squash the commits for this PR.
