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.

The original changes had to be reverted due to a memory leak in
SkBaseDevice from SkTextBlobCacheDiffCanvas. This has been addressed by

Original change's description:
> fonts: Set up remote glyph caching to push fonts.
>
> 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.

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.

Here is a simple API for the object that pins, and
how it flows through the cache.

The strike cache and the glpyh cache have been friends
for a long time. Untangle this twisted relationship.

Move all the information for handling nodes into
SkStrikeCache. Having all the cache organization
in SkStrikeCache will localize all the Chrome
pinning machinery to this class.
