HTTP/2: Optimize check for CONNECT method in header creation

`String.upcase/1` by default iterates over the graphemes in the
input string which can be relatively slow. Since we're only interested
in case-insensitive equality, we can write a small custom equality
checking function that can avoid creating new terms and can return
early.

Using a charlist is slightly faster than passing `"CONNECT"` as a
binary.
