The remote glyph cache tests assume that the strike cache will not
change during a test. This is not true because other test also
mutate the strike cache. This is causing flaky tests.

If the client finds that the server re-initializes a cached path/image,
we consider this an error and invalid data. But since we might
initialize a glyph using a fallback on the client, and receive the
correct version from the server later, this is not longer true.

When allocating the mask for a fallback glyph, we allocate it on the
arena on the SkScalerContext while the image belongs to a glyph on a
different cache. This can lead to use-after-free bugs if accessing the
image after the context owning that memory is destroyed. Fix this by
allocating on the arena from the owning cache.

This is almost entirely mechanical.

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.
