LibVT+Kernel: Separate the caret shapes and its steadiness

Browse source 
Currently CursorStyle enum handles both the styles and the steadiness or
blinking of the terminal caret, which doubles the amount of its entries.
This commit changes CursorStyle to CursorShape and moves the blinking
option to a seperate boolean value.
