* 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 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.

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.

Some platforms define uint32_t as "unsigned long" rather than "unsigned int".
The %d format specifier is mismatched and the C99 format macros are the only

This change introduces new fields on `lv_disp_drv_t` that allow to
specify the size of the full display and the offset of the display
subsection that is being rendered to. The values are used to transform

This commit replaces the current `actual & expected` check in
`lv_btnmatrix_has_btn_ctrl` with `(actual & expected) == expected`. This
is required to make the function work with ORed control flags because
otherwise a parity in *any* bit will result in a return value of `true`
even if not all expected bits are set.
It was used to position the text in one line text areas where the label is shorter then the text area itself.
However, setting min_width=100% in case of one line text area ensures that the label is at least as wide as
the text area. This way the normal text_align style property can be used too.

Prior to this commit, when the title string was empty and the close
button disabled, an extra empty line showed at the top of the message
box. This commit prevents adding the title label unless it has content
or is needed as a spacer for the close button.
As a positive side effect, this also prevents the default "text" from
displaying when NULL is passed as the title.

This adds a new function lv_msgbox_get_active_btn that works analogously

The index is more convenient for comparison in localized applications as
it doesn't depend on the current language.
