fonts: Handle fallback to using paths for text rendering for remoting.

SkRemoteGlyphCache only sends images for glyphs, even for cases where
the gpu falls back to drawing text as paths. This includes cases in
SkDraw::ShouldDrawTextAsPaths and when the glyph exceeds the max bounds
that can fit on the atlas. Fix this by identifying these cases in the
renderer and sending paths instead.

Note: We still don't handle distance field text correctly.
