Add hide-soft-keyboard-on-startup property

If its set to `true` in termux.properties file, then soft keyboard will automatically be hidden on Termux App start to solve issues for when users use hardware keyboard and soft keyboard is automatically opened and wastes terminal screen space.

The `TermuxPropertyConstants` classes has been updated to `v0.5.0`. Check its Changelog sections for info on changes.

Fixes termux#1978
