Gradle plugin for generating weaver files

[jaydeluca]

I took a stab at creating a gradle plugin to replace the makefiles for the weaver generation tasks, inspired by the semantic-conventions-java approach

I imagine this will need to evolve as we figure out the needs of running it for multiple modules (like #2362), aside from just the ibm-mq-metrics, which this was mostly focused on solving for.

I'm still not sure if this is the best approach, there are some others that are still being discussed in open-telemetry/weaver#792 but wanted to see what this might look like

It's been a while, but i just went back and re-tested everything and its good to go from my perspective.

I just added one more small change to allow invoking the weaverGenerate jobs from anywhere (so you can do ./gradlew :ibm-mq-metrics:generateWeaver from root or ../gradlew :ibm-mq-metrics:generateWeaver from within the ibm-mq-metrics directory

@atoulme @mcmho is this good to go from your perspective?

I think this is a job well done! Thanks for the gradle plugin.
