fuzztest_ioerrors: Combine test cases to improve performance.
...
This way the io error test will crash on either out of memory or
stream io error, whichever occurs first.

Fuzztest: run whole corpus for non-embedded targets.
...
This is a tradeoff between test time and test coverage.
After consideration, I've decided it is better to catch
potential problems earlier even though it increases test
time by ~15 seconds.

Reduce number of fuzztest iterations to speed up tests.
...
Through repeated runs, it will still get the same coverage.
And the OSSBuild fuzz infrastructure has much more CPU power anyway.

Fuzztest: don't assert when re-encoding fills up the buffer.
...
Turns out the special case for 0-length input for fixed length bytes
field can cause a quite large message expansion on re-encode. The
assertion is not very useful for finding actual bugs, so this silences
it to avoid it disturbing fuzzing.

Try to fix fuzztest issue on Windows.
...
The buffer length was a bit small so most of the corpus
messages wouldn't fit in it, causing pipe write to hang
until the process exited.
