Create termux-shared library package for all termux constants and shared utils

The termux plugins should use this library instead of hardcoding "com.termux" values in their source code. The library can be included as a dependency by plugins and third party apps by including the following line in the build.gradle where x.xxx is the version number, once its published. `implementation 'com.termux:termux-shared:x.xxx'` The `TermuxConstants` class has been updated to `v0.17.0`, `TermuxPreferenceConstants` to `v0.9.0` and `TermuxPropertyConstants` to `v0.6.0`. Check their Changelog sections for info on changes. Some typos and redundant code has also been fixed.
