tools: logo: split bmp arrays from bmp_logo.h

Browse source 
The generated header bmp_logo.h is useful even outside common/lcd.c for
the logo dimension.  However, the problem is, the generated bmp_logo.h
cannot be included multiple times because bmp_logo_palette[] and
bmp_logo_bitmap[] are defined in the bmp_logo.h.

This patch fixes this by defining these arrays in another header
bmp_logo_data.h and in bmp_logo.h only declaring these arrays.
