* PXP: Added basic PXP acceleration
PXP accelerated features:
- fill (+ opacity)
- BLIT (+ opacity)
- recoloring (+ opacity)
- color keying (+ opacity)
Recoloring + color keying simultaneously not supported.

* PXP: Added abstraction for interrupt handling
Previous imlpementation used IRQ polling on PXP, which doesn't allow
real CPU offload. Therefore added set of callbacks for interrupt
handling that should be implemented by user, with possible RTOS
integration.
Default/example implementation of callbacks for bare metal and FreeRTOS
provided (lv_gpu_nxp_pxp_osa.c), enabled by
LV_USE_GPU_NXP_PXP_DEFAULT_OSA switch, accesible via pxp_default_cfg
structure.

* PXP: Optimized cache flushing
Previous implementation flushed areas of (LCD width * object height)
size. Cache flush is expensive operation and flushing line by line,
smallest possible area, boost performance by shortening time spent on
cache flushes.

* PXP: Fixed ifdefs - Removed LV_USE_GPU, fixed internal config
LV_USE_GPU is not intended as a global GPU enable switch. It's used only
for gpu_blend_cb and gpu_fill_cb callbacks, which are obsolete. This
patch removes LV_USE_GPU dependency for PXP code, so it's enabled only
with LV_USE_GPU_NXP_PXP symbol.
Added missing symbols to internal conf, so automatic testd can pass
build step.

* PXP: Default OSA changed to PXP auto-initialization
Auto init feature added so if user run FreeRTOS or bare-metal, no PXP
Init code is required. Renamed symbol to be more clear.

* PXP: Documentation moved to docs repo

* PXP: Fixed alpha configuration
- Coverity issue: AS blend config used uninitialized structure. No
impact on functionality, as blend module is not used (porter-duff blends
in this case)
- Alpha config fixed - swapped alpha values produced different result
from SW render
