Lua -- Fix device hang when scroll function active on clear_screen

I previously noticed that manually clearing the framebuffer while scroll
function was active caused lua to crash

I could reproduce in sim and on device but I thought using the plugin
supplied rb->lcd_clear_screen was immune to this issue

Unfortunately some devices exhibit this behavior with the plugin function
as well

This patch adds rb->lcd_scroll_stop() before lcd_clear_screen at lua start-up
and to the supplied include file lcd.lua
