Kconfig: Add choice of framebuffer mode

Browse Source 
Rename `FRAMEBUFFER_KEEP_VESA_MODE` to `LINEAR_FRAMEBUFFER` and put
it together with new `VGA_TEXT_FRAMEBUFFER` into a choice. There are
two versions of `LINEAR_FRAMEBUFFER` that differ only in the prompt
and help text (one for `HAVE_VBE_LINEAR_FRAMEBUFFER` and one for
`HAVE_LINEAR_FRAMEBUFFER`). Due to `kconfig_lint` we have to model
that with additional symbols.
