panfrost: XMLify the rest of shader_meta

panfrost: XMLify the rest of shader_meta

This contains a bit of everything, so just XML for this commit. The rest
of the series will be slowly moving over to this representation.

The one noteworthy addition is the rename of "No MSAA" to
"Single-sampled lines". This came about due to a buggy branch that
forgot to set this bit. Ths worked, with the caveat of the following
tests failing with a single-sampled framebuffer:

   dEQP-GLES2.functional.rasterization.interpolation.basic.line_loop_wide
   dEQP-GLES2.functional.rasterization.interpolation.basic.line_strip_wide
   dEQP-GLES2.functional.rasterization.interpolation.basic.lines_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.line_loop_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.line_strip_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.lines_wide
   dEQP-GLES2.functional.rasterization.primitives.line_loop
   dEQP-GLES2.functional.rasterization.primitives.line_loop_wide
   dEQP-GLES2.functional.rasterization.primitives.line_strip
   dEQP-GLES2.functional.rasterization.primitives.line_strip_wide
   dEQP-GLES2.functional.rasterization.primitives.lines
   dEQP-GLES2.functional.rasterization.primitives.lines_wide

That is, this bit controls the behaviour of line rasterization with
multisampling. This is required to implement the divergent behaviours
described in the OpenGL ES 3.2 specification sections 13.6.1 ("Basic
Line Segment Rasterization") and 13.6.4 ("Line Multisample
Rasterization"), where setting this bit corresponds to the former
(single-sampled) behaviour.
