Support viewing/changing backend shaders in Viewer
Previously, all backends allowed the SkSL to be edited, and GL allowed
GLSL to be edited. Now any backend's source can be seen, and they can
all be edited (other than SPIR-V). Tested with HLSL and SPIRV. I don't
have a Mac available, but MSL should work, too.
