feat(gpu): reattach nxp pxp vglite accelerators(#3322)

* feat(pxp/vglite) Attach NXP GPUs to the new draw context.

Create a single NXP draw layer on top of PXP and VGLITE.
Extra changes:
1. Add VGLITE image blits acceleration.
2. Reenable blit split workaround for quality issue in RT500.
3. Increase threshold from 32 to 5000 px to fill/blit with both PXP and VGLITE.
4. Allow to enable both PXP and VGLITE. Add a fallback mechanism:
- by default the PXP will try to accelerate. if that is not supported (or fails
due to threshold limit condition from 3.) then it will fallback to VGLITE.
- if VGLITE does not support that feature (or fails due to threshold limit
condition from 3.) the it will fallback to CPU.

* feat(vglite) Add VGLITE support to draw the backgroud of rectangles.

optim: draw only a circle when radius has value LV_RADIUS_CIRCLE.
optim: to draw rounded corners, use cubic bezier curves

* feat(vglite) Add VGLITE support to draw arcs.

Use up to 4 bezier curves to optimize the drawing of an arc.
The arc curve has to be constant when growing the angle:
for this we compute sub-arc based on a best approximation of quarter-arc.
use dichotomy to find the sub-arc 't' param, instead of tangent approximation.

* fix(pxp/vglite) Avoid calling the blend callback from image decoded callback.

Add lv_gpu_nxp_pxp_blit_transform() and lv_gpu_nxp_vglite_blit_transform().
This will simplify a lot the fallback mechanism and the way of adding new
image decoded features.

* feat(pxp) Add image rotate 90x.

Simplify the two steps process by adding the blit_cover and blit_opa functions.

In order to rotate or recolor with opacity, two steps must be fallowed:
1. Run the operation without opa.
2. Blend the result by applying the opa.
(MGG-469)

Obs:
Recolor and rotate is currently not supported with opa or alpha channel.(MGG-883)

* fix(pxp) Separate blit simple by the blit with transformation.

While we run into blit with transformation we have to
decide if the operation needs to be done in one or two steps.
Blit with color format (opa or alpha or chroma key) - require one step: blit_cf().
Blit with rotate or recolor but no color format - require one step: blit_cover().
Blit with rotate or recolor + opa or alpha - require two steps:
blit_opa() = blit_cover() + blit_cf().
Blit with rotate or recolor + chroma key - not supported yet.

* fix(nxp) Fallback to software callbacks if need for argb8565 support.

During rendering, LVGL might initializes new draw_ctxs and start drawing into
a separate buffer (called layer). If the content to be rendered has "holes",
e.g. rounded corner, LVGL temporarily sets the disp_drv.screen_transp flag.
It means the renderers should draw into an ARGB buffer.
With 32 bit color depth it's not a big problem but with 16 bit color depth
the target pixel format is ARGB8565 which is not supported by the GPU.
In this case, the NXP callbacks should fallback to SW rendering.

* fix(pxp) Fixed the color key recoloring on 16 bits color depth.

1. Fixed the arguments of lv_color_mix(), previously was using an inversed logic. But it works anyway.
2. Use LV_COLOR_SET_X for adjusting the channels on both 16 and 32 bits. Fixed the max values.
