net/http: add errors.As support for x/net/http2.StreamError
To make it easier to extract the HTTP/2 error code (if any) from
net/http errors, implement an As method on the vendored copy of
golang.org/x/net/http2.StreamError. The new As method lets users work
with the vendored error type as though it were the x/net/http2
StreamError.
Fixes #53896.
