Added|Fixed: Do not show AutoFill UI on Termux start and add support for usernames

Browse Source 
- The AutoFill type and hints are no longer hardcoded in `TerminalView` class and `TermuxActivity` layout xml. They are dynamically set to required values before making a manual AutoFill request and reverted back afterwards to default values. The hardcoded value `AUTOFILL_TYPE_TEXT` returned by `getAutofillType()` was causing the AutoFill UI to show on Activity starts, this will return `AUTOFILL_TYPE_NONE` by default now so that AutoFill UI isn't shown automatically.
- The AutoFill importance is no longer hardcoded in `TermuxActivity` layout xml and is returned by `TerminalView` class itself by `getImportantForAutofill()`.
- The AutoFill function in `TermuxActivity` for making a manual AutoFill request is moved to `TerminalView` class. This and moving of hardcoded values to `TerminalView` class mentioned above is done as complete logic of AutoFill should be handled by `TerminalView` class itself and not scattered in various places.
- The Terminal context menu now supports AutoFilling a username. Note that GBoard/Google Password Manager seems to have a bug where it will still show `Pick a saved password` instead of username, even though `AUTOFILL_HINT_USERNAME` is being requested, however it will still AutoFill a username of selected entry correctly.
- Pressing the back button to close the keyboard will also cancel the current manually requested AutoFill request and UI will not show when keyboard is opened again.
