Pico Scroll/Unicorn: Fix static memory alloc for Pico W.

Pico Scroll and Pico Unicorn were allocating static buffers for gamma and font data respectively.

Make Pico Scroll's `__bitmap` static.

Move Pico Unicorn's three GAMMA tables to one 14-bit table in "pimoroni_common.hpp". Rename "GAMMA" to "GAMMA_8BIT".
