http2: add ConfigureTransports
The ConfigureTransport function doesn't provide any way to get at the
http2 Transport it creates, making it impossible to configure transport
parameters such as ReadIdleTimeout.
Add a ConfigureTransports function which returns the http2 Transport.
The very similar names are unfortunate, but they'll sort next to each
other in godoc and the pluralized ConfigureTransports hints at its purpose:
it lets you configure both the http and http2 transports.
Fixes golang/go#40201.
Updates golang/go#41721.
