When a SD file is selected to print
save the DOS 8.3 extension into EEPROM.
After a power outage, the correct file extension is then
selected instead of always assuming it's ".gco"
This allows users to recover ".g" files.

There is no need to read one byte at a time. We can simply
read the whole block in one go. This saves some flash memory.

We can just read the whole EEPROM block since short filenames
are always null terminated. strcat_P will then apply the file extension
at the correct position.

If the saved printing type was USB, then EEPROM_FILENAME
does not contain anything. The firmware should also
not be trying to open a file on a SD card which is maybe
not even mounted.

There is no need to restrict how often the message is rendered.
It was being restricted to render every 1 second. We don't do
this for most of the static menus. So I propose this 1 second period
be removed.

My plan is to re-use this function in M79
in a later commit. The firmware doesn't
have a dedicated parser like Marlin 2.1
so this is my attempt to not duplicate the parsing of a quoted string in G-codes

The idea is to have the host ping the printer periodically with a M79 to
enable certain features/UI. Using the usb_timer is not a good solution
for this as it depends on seeing a 'G' character
The LCD code, or whatever code is implementing the new functionality
will need to include host.h and check whether M79_timer_get_status()
returns 0 (timer not running) or 1 (timer is running).
I created a new file for the code host.cpp which we can use to expand
host related functionality and not clutter Marlin_main.cpp further.

Setting this state notifies PrusaLink/PrusaConnect
that the printer is waiting for user input (attention).

power_on should not be modifying
EEPROM_MMU_ENABLED. The code is never
executed unless it's already been set.
Only disable EEPROM_MMU_ENABLED through Buttons::DisableMMU
