* Clear color values are not explicitely sent to the rendering backend as-is.
Previously, converting from Color32 to Rgba caused an srgb->linear conversion. This conversion is incorrect if the backbuffer doesn't perform automatic conversion from linear->srgb (lack of this conversion is generally what egui assumes!).

The Vivante GPU on many STM32MP1 based boards does not support sRGB
as an internal format.
Introduce a check for sRGB support and default to `RGBA8` internal format
if not supported.
Additionally the STM32MP1 needs to be checked for `GL_ARB_vertex_array_object`
Closes#1991
