Disable terminal keyboard on eglfs and linuxfb

Unify the behavior for eglfs, linuxfb and kms. The relevant code is
now moved from kms into fbconvenience.

From now on, on all three platforms, terminal keyboard input is turned
off by default. This feature can be disabled by setting
QT_QPA_ENABLE_TERMINAL_KEYBOARD to 1. This is similar to what the
evdev-based keyboard handler did in QWS in Qt4.

[ChangeLog][QtGui] The main Embedded Linux platform plugins (eglfs,
linuxfb, kms) are changed to behave identically with regards to
terminal keyboard input: it is turned off by default on all of these
platforms. If this feature is not desired, it can be disabled by
setting the environment variable QT_QPA_ENABLE_TERMINAL_KEYBOARD.

Task-number: QTBUG-36394
