Code Review

This pull request reorganizes tests for fragment shader uniforms, adding more comprehensive coverage for various uniform types and removing redundant tests. A new uniforms directory is added for the new test shaders. The changes also include a fix for an indexing error in painting.dart when creating UniformFloatSlot objects. I have one comment regarding a potential issue in the implementation of this fix.

LGTM, thanks! Do we need a followup for things like Mat3?

LGTM, thanks! Do we need a followup for things like Mat3?

Yup. I was going to add those in when implementing getUniformMatX

Enables fragment shader test for impeller (fixes mat2 on vulkan) (flutter#181013)

This rearranges the packing of mat2 fields in structs which was causing
an existing fragment shader test to fail.

The test still doesn't work on Metal, but this PR fixes it for Vulkan. I
suspect the fix for metal may be similar but since the uniforms aren't
in a virtual struct the code isn't hitting this fix.
