29121ebd9e Avoid integer overflow in SkIcoCodec and SkImageInfo
Original Commit Message:
"""
Avoid integer overflow in SkIcoCodec

Definitely good to avoid overflow here.

FWIW, this looks to be harmless for Android's current use.
They will just fail later on when trying to allocate the
bitmap.

BUG=skia:5857
"""

With the new test, ASAN also caught an integer overflow
bug in SkImageInfo.  Fix this as well.

d0375bc460 Fix bmp RLE "bug"
Chromium's test suite contains an RLE image that reports a certain
file size in the header, but then contains additional encoded data.
Our bmp decoder would only decode half of the image, before stopping.

With this fix, we check for additional data before returning
kIncompleteInput.

If this lands, I will upload the test image to the bots.

Also adding an invalid image test to CodexTest.

b61e206138 Add tests (and fix!) for known bad ICO files.
We previously saw crashes decoding bad ICO files. Add tests for
known bad files.

While testing, I learned that one of them still crashes. Check for
large offset and size separately to fix the crash.
