Bug: oss-fuzz:6274
Even if a frame does not have enough LZW blocks to decode all rows,
(which is unknown until we actually decode them), it is marked complete
once there are no more LZW blocks.
When decoding, even if we've decoded all LZW blocks, check fRowsDecoded
to determine whether we've actually all the rows. Report the number of
rows decoded so that SkCodec can fill in the remaining ones.

Bug: b/65290323
If a webp file is truncated such that no rows can be decoded,
WebPIDecGetRGB does not initialize its "last_y" parameter. We use
rowsDecoded (passed as last_y) to determine which remaining rows to
fill.
Check the return value of WebPIDecGetRGB. If it fails (returns null),
or rowsDecoded is <= 0 (matching Chromium's check), return
kInvalidInput, since there is nothing to draw.
Note that this is a change in behavior for Android. Previously we
would decode an empty webp to just a transparent/black rectangle,
whereas now we simply fail. I think this is a change for the better.
Add a test which truncates a file to have 0 rows available and attempts
to decode it. msan verifies that we no longer depend on the
uninitialized value.
Stop attempting to test decoding subsets from an incomplete webp (in
CodecTest.cpp). Unless we have decoded the portion covered by the
subset, this will fail.
Remove test images inc0.webp (from both dm/ and colorspace/) and
inc1.webp. These just decode to transparent rectangles. Replace them
with inc2.webp and inc3.webp, which decode part of the image and then
have to fill with transparent.

Previously, SkGifCodec treated an error in the LZW data as incomplete,
since we can still draw the partially decoded image. But a client doing
incremental decodes needs to distinguish this from truly incomplete
data. In the case of an error, the client should not attempt to provide
more data and decode again.
Add kErrorInInput, and return it when SkGifCodec sees a fatal error.
Treat it the same as kIncompleteInput when it comes to filling and DM.

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.)
