Increase id3v2 max item size on high mem targets

As per multiple user requests:
https://forums.rockbox.org/index.php/topic,53319.msg

The acceptable size for id3v2 fields currently maxes out at
240 bytes on targets with more than 2MB of memory.

The comments field, especially for Podcasts, can sometimes
contain significantly more characters than Rockbox allows.

The limit for devices with more than 8MB of memory
is increased to 500 bytes for individual fields, and
to 1800 bytes for the buffer containing all fields.
