De-bump AGP to 7.3.1 and do not use addGeneratedSourceDirectory (#3…

…5631)

Summary:
Pull Request resolved: #35631

Fixes #35592
I'm de-bumping AGP from 7.4 to 7.3 as per #35592. There is no stable release
of AGP that is working fine with the `addGeneratedSourceDirectory` API for resources.
Here I'm reverting to use the older APIs.

Changelog:
[Internal] [Changed] - De-bump AGP to 7.3.1 and do not use `addGeneratedSourceDirectory`
