To allow flickerfree boot the EFI console code does not call
grub_efi_set_text_mode(1) until some text is actually output. Depending
on if the output text is because of an error loading, e.g. the .cfg
file, or because of showing the menu the cursor needs to be on or off
when the first text is shown. So far the cursor was hardcoded to being
on, but this is causing drawing artifacts + slow drawing of the menu as
reported here: https://bugzilla.redhat.com/show_bug.cgi?id=1946969
Handle the cursorstate in the same way as the colorstate to fix this,
when no text has been output yet, just cache the cursorstate and then
use the last set value when the first text is output.
