[FR]: Migrate from oss-licenses-plugin to Licensee

[Goooler]

Is there an existing issue for this?

• I have searched the existing issues

Describe the problem

Now we depend on com.google.android.gms:play-services-oss-licenses to generate the license page, which is not configuration cache compatible and relies on AppCompat themes. We can migrate to Licensee instead, which will eliminate AppCompat libs and significantly decrease the app size.

I can't find much difference in the app size after removing the OSS license plugin.
Before: 8597201 bytes.
After: 8283953 bytes.
It reduced the size of the installation package by 4%.
