ref(nestjs): Vendor nestjs-core instrumentation

[nicohrubec]

Vendors @opentelemetry/instrumentation-nestjs-core into the SDK with no logic changes. Types from @nestjs/core and @nestjs/common are inlined as simplified interfaces to avoid requiring these packages as dependencies.

Closes #20943

super-l: Looks like OTel switched to SPDX identifiers for their licenses, saves some lines. We could do the same?

e.g.
https://github.com/open-telemetry/opentelemetry-js-contrib/blob/15ef7506553f631ea4181391e0c5725a56f0d082/packages/instrumentation-nestjs-core/src/index.ts#L1-L4

edit: also oxlint conflict

@andreiborza I'll leave the header as is for now so we keep it consistent, but will keep it in mind maybe we can shorten it in a follow-up
