Changed: Use termux-shared

- All hardcoded `com.termux` constants have been removed and will be handled by `TermuxConstants` and `TermuxPreferenceConstants`.
- Fixed issue with losing reference to `TermuxFloatView` in `TermuxFloatService` and destroying view not working.
- Removed unnecessary toasts and fixed custom broken ones by using the one provided by `Logger` class.
- Updated `TerminalView` and `TerminalSession` to latest versions and removed duplicated `TerminalSession` code based on old `TermuxService` and start using `TermuxSession` which will also have consistent shell environment as `termux-app`.
- Removed `SharedPrefernces` management and use the one in `termux-shared` provided by `TermuxFloatAppSharedPreferences`.
- Use action constants defined in `TermuxConstants` for `TermuxFloatService`.
- Use notification constants defined in `TermuxConstants` for `TermuxFloatService`.
- Use `KeyboardUtils` for showing and hiding keyboard.
- Implement logging system based on `Logger` class. Log levels can be changed in `termux-app` settings but require restarting `termux-float` for changes to take effect since both apps run in different processes.
- Fixed potential `IllegalArgumentException` when adding and removing `TermuxFloatView` to `WindowManager`.
- Added crash handler so that crash notifications can be shown in `termux-app` at startup.
