Add a new private method to SkCodec that handles Options.fFrameIndex:
- Check to ensure the index is valid
- Call onGetFrameCount to force parsing the stream
- Recursively call getPixels (it should be complete, so no need for
incremental decoding) to decode the prior frame if necessary
- Zero fill a RestoreBGColor frame
Call the method in getPixels and startIncrementalDecode, and remove
duplicate code from GIF and WEBP.
Remove support for scaling frames beyond the first, which is currently
unused.
Preserve the feature of SkGifCodec that it will only parse to the end
of the first frame if the first frame is asked for. (Also note that
when we continue a partial frame, we won't force parsing the full
stream.) If the client only wants the first frame, parsing the rest
would be unnecessary. But if the client wants the second, we assume
they will want any remaining frames, so we parse the remainder of the
stream. This simplifies the code (so SkCodec does not have to ask its
subclass to parse up to a particular frame).
Update tests that relied on the old behavior:
- Codec_partialAnim now hardcodes the bytes needed. Previously it
relied on the old behavior that GIF only parsed up to the frame being
decoded.
- Codec_skipFullParse now only tests the first frame, since that is the
case where it is important to skip a full parse.

SkCodec sets fRequiredFrame to be the earliest possible frame that a
given frame can depend on. e.g.
- Frame A fills the screen, Keep
- Frame B does not cover A, Keep
- Frame C covers B but not A, and is opaque
Frame C can depend on either A or B. SkCodec already reports that C
depends on A. This CL allows a client of SkCodec to use either A or
B to create C.
Also expose the DisposalMethod. Since any frame between A and C can
be used to create C except for DisposePrevious frames, the client
needs to be able to know the disposal method so they do not try to
use such a frame to create C.
Further, the disposal method can be used to give the client a better
idea whether they will continue to need a frame. (e.g. if frame i is
DisposePrevious and depends on i-1, the client may not want to steal
i-1 to create i, since i+1 may also depend on i-1.)

Subclasses sometimes try to read fOptions, but it used to not get set
for full decodes. As a result, they might be reading the Options from a
previous scanline/incremental decode. In addition to being wrong, this
is bad in the case of an fSubset pointing to a rectangle that no longer
exists.
So set fOptions in getPixels, prior to any attempts to read it by sub-
classes. Use a different workaround for the webp/incomplete bug. Set
fSubset to null prior to calling fillIncompleteImage. It can only be
non-null for webp, and in that case we do not want the fill call to
be using the subset width.
Modify the Codec_jpeg_rewind test to use an incomplete image, so that
it will also test fillIncompleteImage.
DM tests of inc0.webp and inc1.webp will verify that the incomplete
bug has not resurfaced.

An RLE bmp reports how many bytes it should contain. This number may be
incorrect, or it may be a very large number. Previously, we buffered
all bytes in a single allocation. Instead, use a fixed size buffer and
only read what fits into the buffer. We already have code to refill the
buffer if there is more data, so rely on that to keep reading.
Choose an arbitrary size for the buffer. It is larger than the maximum
possible number of bytes we need to read at once.
Add a test with a test image that reports a very large number for
the number of bytes it should contain. With the old method, we would
allocate 4 gigs of memory to decode this image, which is unnecessary
and may result in OOM.

In SkBmpCodec, if the header size does not match a known header,

In addition, this fixes a bug where we attempt to read too much data

and a size reported by the "BMP" may be larger than SSIZE_MAX, this
will crash when reading from a file.

It also speeds up my local runs, since most of the time is spent in
