feat(opentelemetry): add support for OTEL v2

[chris-olszewski]

What was changed

Add a new package that supports OTEL v2 interceptors.

Key changes:

• Package targets v2 of all OTEL packages it consumes
• Removed spanExporter support
• Removed deprecated OpenTelemetryWorkflowClientCallsInterceptor alias
• Provide our own IdGenerator that consumes a named random stream to make span ID generation deterministic and preventing it from affecting randomness in workflow.

Reviewers should primarily focus on reviewing the second commit as it is the diff between v1 and v2 of this package. The first commit is a straight copy of the v1 package into the v2 directory.

Replacing #1951

Why?

We are adding a new package instead of bumping the dependency on the old one for a few reasons:

• We do not want to perform a major semver bump on just one of our packages, it confuses our versioning story.
• We do not want to attempt to support both OTEL major versions in the same code as that becomes extremely hacky and hard to read.
• We want to correct mistakes in the first OTEL package: removing deprecated functionality and moving to use named random streams so adding these interceptors to a worker no longer can trigger NDE if attempting to replay a workflow started without them.

Quick note on James comment from previous PR

Btw, we now have a preloadedModules bundler option, which may help reduce the overhead associated with per-workflow loading of the OpenTelemetry library.

I don't think this is viable here as registering the tracer provider/context manager in workflow/index.ts mutates the loaded frozen OTEL module.

Checklist

1. Closes [Feature Request] Add support for opentelemetry v2 #1658

2. How was this tested:
   Most tests were directly kept. Replay tests had to be dropped as we changed how we used randomness so histories are incompatible. Added history replay tests for this package as regression tests for future changes to this package.

3. Any docs updates needed?
   Once this moves out of experimental, docs page should update to suggest using this package instead of v1.
