This change makes it easier to move x/net/http2 into std.
Moving the http2 package into std and importing it from net/http
(rather than bundling it as net/http/h2_bundle.go) requires
removing the http2->net/http dependency. Moving tests into
the http2_test package allows them to continue importing net/http
without creating a cycle.

This change adds initial support for the PRIORITY_UPDATE frame
introduced in RFC 9218.
Clients can now use a new exported function to write PRIORITY_UPDATE
frames easily. However, sending PRIORITY_UPDATE frames to the server
does not currently cause any behavior changes: we only use
PRIORITY_UPDATE frames to adjust stream priority when the RFC 9218 write
scheduler is being used for a particular connection. However, this
scheduler is not currently usable yet from any configuration surfaces
exposed to the user.
For golang/go#75500

Replace ad-hoc pre-synctest synchronization with testing/synctest.
Many of the http2 package tests use a custom-built fake time
implementation and a idleness-detection mechanism based on parsing
goroutine stack dumps. Experience with this approach to testing
eventually led to the development of the testing/synctest package.
Switch over to testing/synctest.
The synctest package became available as an experiment in Go 1.24
(only when GOEXPERIMENT=synctest is set), and was fully released
with some API changes in Go 1.25.
- Use the released synctest API on Go 1.25.
- Use the experimental API (synctest.Run) on Go 1.24 when
GOEXPERIMENT=synctest is set. (Note that we set this on trybots.)
- Skip tests on Go 1.24 when GOEXPERIMENT=synctest is not set.
The x/net module requires go1.24, so older versions
can be disregarded.

Client and server tests both write frames to a test connection
and read frames back. Frame reads are usually paired with
test expectations.
Unify the API used for frame reads/writes in tests.
Introduce a testConnFramer type that implements a common set
of read/write methods, and embed it in both client and server
test types.
