  Allow EOF as empty statement too

Use the existing nl-or-end as the empty statement so that a bare EOF
qualifies.

Create a general-purpose atmega32u4 snek installer and
replace the single-device versions.

  Log Message:
  -----------
  Use __flash for AVR code instead of PROGMEM

This uses the GCC memory space attribute so that the compiler will
automatically generate the correct memory access instructions instead
of requiring manual use of various progmem APIs. This both simplifies
the code and reduces its size.

The new version of GCC leaves more RAM available; take advantage of that
by increasing the heap size to 1kB and the value stack to 32 elements.

On the atmega4809, avr-libc doesn't set E2END to be the last offset,
rather it's the last address. Use EEPROM_SIZE instead, which seems
to be the size - 1.
