Reland: "Switch to using vp9-lossless for VideoEncodeAccelerator test files."

Fixes nits from thestig@ and compilation failure on Windows. PS#1 is the
original change, later PSs are with the fixes.

------------------------------
These raw files were large and are slowing down the fuzzer process;
this saves 13,416,948 bytes. I've confirmed via MD5 hashes that
the decode path and the yuv path generate the same output data.

BUG=960139
TEST=verify MD5 hashes between compressed and uncompressed variables.
