RFR: 8300997: Add curl support to createJMHBundle.sh

[Eirik Bjorsnos]

Please review this PR which updates make/devkit/createJMHBundle.sh to add support for curl instead of wget when downloading JMH dependencies.

This would reduce friction for MacOS devs who would like to run micros without installing wget first.

File download is extracted to a function taking the Maven directory, artifactId and version as input. The function builds the correct download URL and checks which of curl / wget is available.

Tested on MacOS 12.6.2 and Ubuntu 20.
