…ntation (#15732)

Part of #15730

Noticed that this is not really happening otherwise, so if we are not
adding the `HttpInstrumentation` we now make sure to extract incoming
traces ourselves! This will unlock us not adding that instrumentation
when tracing is disabled.

Also includes #15731
as a side effect.

Small optimization to avoid unnecessary work.

Closes #13700

This also adds tests for unhandled rejections handling, which we did not
really have before.

## Description

`captureLog` takes in a `log` interface as well as a scope, and
constructs a serialized log to send to Sentry. Instead of directly
sending the serialized log, it adds it to a log buffer that is flushed
based on some strategy. As a fallback, the buffer flushes itself when it
gets over 100 items, which ensures we never get a payload thats too
large.

The browser and server runtime client are expected to add more advanced
flushing strategies on top of the simple implementation exposed in
`captureLog`. This will be done in future PRs.

The serialized log that is constructed by `captureLog` send logs via the
opentelemetry format. This is temporary, in the future we'll switch to
the sentry logs protocol, but while that gets ready we are using the
OTEL one.

## Next steps

1. Add flushing strategy for server-runtime-client
2. Implement top-level API methods as per develop spec
3. Add support for paramaterized strings
4. Add integration tests to validate envelope gets sent correctly

This just makes it a bit more disoverable for poor souls like me
searching for "alpha" in this doc

Follow-up for #15710

The server config was still processed by Nuxt (not only Nitro) because
the file was imported in a plugin template. This code can be deleted
now, as the Sentry server config should only be processed on the
Nitro-side.
