Reduce max input size in parser fuzzer

Still seeing stack overflows for $$$$$x style input, let's reduce
the input size limit further...

Further limit max input size in parser fuzzer

It's easy to cause stack overflows with degenerate cases like
"$$$$$x" repeated thousands of times. We have no interest in
addressing these.

Make the input size smaller to hopefully avoid these stack
overflows.

Add fuzzer for function JIT

This is a basic fuzzer for the function JIT, which looks for
crashes and sanitizer violations only, and does not try to detect
differing behavior yet.

Limit max length for parser fuzzer

We're getting some very large inputs (~500KB) on OSS-Fuzz, which
slot down performance a lot. Let's try limiting this, starting
with a still fairly large value of 64KB.

Also remove the max_execution_time limit, so that slow test cases
cause a genuine libfuzzer timeout and we may investigate them.
