Add hooks to notify the embedder if there is a cache miss during draw.
Also remove the reference to SkStrikeClient from SkTypefaceProxy and
SkScalerContextProxy, since the proxies can outlive the client.

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.

When deserializing glyphs in the SkRemoteGlyphCache, we allocate from
the arena for the SkGlyphCache but don't account for it in the total
memory used by the cache. Fix that and avoid exposing the SkArenaAlloc
from SkGlyphCache, since that can result in such brittle use.

Currently the SkStrikeClient is designed to pull fonts from the server
on demand, and to pre-fetch a batched request by analyzing the ops using
a SkTextBlobCacheDiffCanvas. This change modifies the design to support
a push based model, where the server pushes fonts required by the client
and sets up the requisite SkGlyphCaches on the client prior to
rasterizing the ops.
This model still relies on the SkTextBlobCacheDiffCanvas for analyzing
the glyphs required for rasterizing an op. The glyph caches required for
raster are locked and missing glyphs to be sent to the client are tracked
by the SkStrikeServer. The embedder can serialize this font data at any
point, but must ensure that this data is deserialized by the
SkStrikeClient at the remote end, before rasterizing any ops analyzed
prior to serialization. Any refs on the caches are released once the
font data is serialized by the server.
The locking of glyph caches relies on the embedder providing discardable
handles. These handles can be created on the server and serialized to be
sent to the client, and map to an instance of SkGlyphCache. This allows
the server to control the lifetime of the caches on the client.
