VT: Bump font size limitation to 64x128 pixels
This moves 32x32 font size limitation checking down to drivers, so that
fbcon can allow large fonts.
We still keep a limitation to 64x128 pixels so as to have a simple bounded
allocation for con_font_get and in the userland kbd tool. That glyph size
will however be enough to have 128x36 characters on a "16/9 8K display".
