ref(node): Vendor @fastify/otel (#21099)

Vendors `@fastify/otel@0.18.1` into the SDK with minimal changes. The
original source is in plain Javascript so this was adapted with minimal
type annotations to make it compatible with the TS compiler of this
repo.

The original instrumentation also had an `ignorePaths` code path, which
relies on `minimatch` as a dependency but was never exposed by the
Sentry integration. For this reason this was already cleaned out so we
can avoid the `minimatch` dependency. Everything else is preserved as
is.

Closes #20162
