Alloc glyph image correctly for SkMask::k3D_Format.
Re-enable the code to test the emboss mask filter, updating it to use
the new emboss mask filter factory.
Add a test to ensure that embossed text is drawn correctly, as before
glyphs did not allocate the proper amount of memory for the k3D_Format
which the emboss mask filter produces.
Fixes SkEmbossMask::Emboss to write the whole of the mul and add planes
to avoid pixel differences and MemorySanitizer errors.
Update the GPU to understand the k3D_Format and use just the alpha
plane, ignoring the mul and add plane which it currently cannot support.
