Federated semantic conventions phase 2

[breedx-splk]

Part of #1814.

This adds a weaver template and gradle script to run weaver and generate these constants files.

In the next phase, we will replace production usages of these constants with references to the new semconv constant classes.

I followed the convention from the opentelemetry-kotlin repo, which expects a local weaver executable to be available. If we hate that and would rather use a docker image (more like the semantic-conventions-java repo), we can change it....I'm flexible.

LOL this also makes it very clear that we will want to change this.

The PR appears to introduce CI-breaking build hygiene issues (missing consumer-rules.pro and missing initial apiDump outputs) and the committed generated Kotlin sources/templates don’t yet conform to enforced Spotless license-header/formatting expectations.

Pull request overview

This PR implements phase 2 of #1814 by introducing a :semconv Gradle module and a Weaver-based codegen pipeline to generate and commit Kotlin attribute-constant classes from the federated semconv registry model (production usage is deferred to later phases).

Changes:

• Adds a weaver registry template + config to generate Kotlin *Attributes constant objects.
• Introduces a :semconv:generateSemanticConventions Gradle task to run Weaver and write generated sources into src/main/kotlin.
• Updates the Android semconv registry/events YAML and commits the initial generated Kotlin constant files.

⚠️ Not ready to approve

The Kotlin generation template currently produces consecutive blank lines in committed generated sources, which is likely to fail Spotless/ktlint checks.

The Kotlin template currently generates consecutive blank lines that are very likely to fail ktlint/Spotless, blocking CI.

⚠️ Not ready to approve

The committed generated Kotlin sources currently violate ktlint/Spotless due to consecutive blank lines emitted by the template, which will fail spotlessCheck.

⚠️ Not ready to approve

The new codegen Gradle task reports a misleading “install weaver” error for all failures, which should be clarified before merging.

semconv/consumer-rules.pro:2

• This consumer ProGuard rules file currently contains only blank lines, which is easy to misinterpret as an accidental leftover. Other modules keep an empty file when no rules are needed; add a brief comment (or remove the whitespace) to make the intent clear.
