fwk/sunflower: enable KEYBOARD_STRICT_DEBOUNCE

Enable keyboard strict debounce to eliminate the ghost key issue.

KEYBOARD_STRICT_DEBOUNCE's comment says we need to make debounce up and
down the same, so we do that as well.

BRANCH=fwk-sunflower-26784
BUG=https://app.clickup.com/t/86et5v7wg
TEST=hold the space key and then press "space" and "1" key will
     not print the ghost key
