http2/hpack: build static table with go generate

As the static version of headerFieldTable in hpack is generated in runtime,
we may use the go:generate to prepare the struct before the initialization phase.
This is supposed to save init time and allocations for many binaries,
as net/http imports hpack.

Before:
init golang.org/x/net/http2/hpack @1.1 ms, 0.097 ms clock, 21240 bytes, 29 allocs
After:
init golang.org/x/net/http2/hpack @0.67 ms, 0.015 ms clock, 8120 bytes, 9 allocs

Fixes golang/go#55881
