This PR does a few related things:

  • Makes the update script much faster to run
  • Adds a CI check that the libfuzzer/ directory correctly reflects the commit that we claim we've vendored
  • Updates our libfuzzer vendor to LLVM 19.x

@Manishearth care to take a look at this? Thanks!

Also do a shallow and sparse clone to make running the script faster.
Avoids version mismatches, supply-chain attacks, etc...
This updates libFuzzer to the latest LLVM version, 19.x. Specifically, commit
`ab51eccf88f5321e7c60591c5546b254b6afab99`.
