With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.
It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.
lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.
All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

Requires addition of viewports and alternate framebuffers to greylib
which are essentially similar to the core implementation except that
the framebuffer can be any size and relationship to a viewport. Drawing
is always fully clipped to the intersecting area.
Adapt oscilloscope.c to the API change. FFT will use the new features
(later update).
Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from
plugin API (must be made incompatible now).

* Adds some additional niftyness like a floating popup display that
is implemented in an OSD library for use by other plugins.
* Speed changes are now gradual for both views and follow a curve
derived from some fiddling around to get a nice feel.
* Refined a few behavioral things overall.
It needs a bit of help from a direct PCM channel callback so it may
capture PCM for waveform display. Also need a few other core routines
to help out for the OSD.
Messes with some keymaps. Some targets need keymaps to access the
different views. Some devices can't support the additional view
because it requires a large buffer ( > 1 s) for samples.
If the plugin buffer is small, they can still use the popup display
since the plugin is also much smaller in that case.
Slow speed waveform needs some refining so it draws gradually like
a real oscilloscope but I'll stick with what it is, for the moment.
