This is just a preparatory patch to move the functions higher in the file,
since these will be called by the grub_prepare_for_text_output() function
that will be introduced in a later patch.
The logic is unchanged by this patch. Functions definitions are just moved
to avoid a forward declaration in a later patch, keeping the code clean.

Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and
a power-button. In their UEFI these are almost always mapped to arrow
up/down and enter.
Pressing the volume buttons (sometimes by accident) will stop the
menu countdown, but the power-button / "enter" key was not being recognized
as enter, so the user would be stuck at the grub menu.
The problem is that these tablets send scan_code 13 or 0x0d for the
power-button, which officialy maps to the F3 key. They also set
unicode_char to 0x0d.
This commit recognizes the special case of both scan_code and unicode_char
being set to 0x0d and treats this as an enter key press.
This fixes things getting stuck at the grub-menu and allows the user
to choice a grub-menu entry using the buttons on the tablet.
