The GPU processing supports 8-bit sensor formats and 10/12-bit packed
formats. Support for 10/12-bit unpacked formats is missing, let's add
it.
10/12-bit unpacked formats use two adjacent bytes to store the value.
This means the 8-bit shaders can be used if we can modify them for
additional support of 16-bit addressing. This requires the following
modifications:
- Using GL_RG (two bytes per pixel) instead of GL_LUMINANCE (one byte
per pixel) as the texture format for the given input formats.
- Setting the texture width to the number of pixels rather than the
number of bytes.
- Making the definition of `fetch' macro variable, according to the
pixel format.
- Using only `fetch' for accessing the texture.

When bayer_unpacked.vert is calculating the center and x/yCoord values
stride != width is taken into account for x/yCoord deltas since it is taken
into account by debayer_egl when setting the x part of tex_step uniform.
But it is not taken into account for the center.x which is just directly
copied from textureIn, leading to the input width sampling covering
the entire input stride instead of just covering the input width.
Use the existing and currently unused stride_factor uniform to pass
the width/stride ratio and correct center.x for this. This fixes
the misrendering seen on x86 laptops which is caused by the CSI2 receiver
there requiring a stride which is a multiple of 32 often leading to
stride != width.

Encode the bayer shader files into a header as part of the build process.
Qcam already compiles the shader files down into a QT resource file which
it references internally.
In order to share the debayering shader programs outside of qcam create a
generic header which both qcam and libcamera can operate from.
