Improve projects searching by allowing field filtering on projects page.

### Problem Statement

At our company we use Sentry a lot across many teams, but after a reorg we might take on an unfamiliar project ... and don't know which of the many projects (or even teams!) a given SENTRY_DSN might be reporting to. It's usually easy to find the DSN as it's configured for the app we might be trying to debug an error in, but any runbook/documentation might be out-of-date or missing.

I had hoped overriding the query-param Project ID number at the end of the Web UI URL would work, e.g. https://sentry.io/organizations/bigcorp/projects/myproject/?project=1234567 , but that doesn't work without the correct project name...

### Solution Brainstorm

Allow the Web UI's "Search for projects by name" field to also accept Project IDs, maybe even recognise & parse that out of a whole pasted DSN url in one of the many forms.
