v4l2_stateful_encoder: Read frame into memory
The performance penalty for reading a file a byte at
a time is quite high. This was done for interleaved
files. Instead read the entire frame into memory in
at a time. Then interleaving is a memory operation
and not a file operation
BUG=b:230654062
TEST=md5 sum matches encode before and after
