Update express integration to be able to ignore layers like router or middleware spans #16555

Description

https://github.com/getsentry/sentry-javascript/blob/develop/packages/node/src/integrations/tracing/express.ts

Similar to the work we did in #16553 for Koa, we should expose ignoreLayers and ignoreLayersType from the underlying OTEL instrumentation.

https://www.npmjs.com/package/@opentelemetry/instrumentation-express

Exposed options:

ignoreLayers accepts an array of elements of types:

• string for full match of the path
• RegExp for partial match of the path
• function in the form of (path) => boolean for custom logic

ignoreLayersType accepts an array of following strings:

• router is the name of express.Router(),
• middleware
• request_handler is the name for anything that's not a router or a middleware
