Daniel Martí 2e29eb57db runtime: remove unused *chantype parameters 
The chanrecv funcs don't use it at all. The chansend ones do, but the
element type is now part of the hchan struct, which is already a
parameter.

hchan can be nil in chansend when sending to a nil channel, so when
instrumenting we must copy to the stack to be able to read the channel
type.

name             old time/op  new time/op  delta
ChanUncontended  6.42µs ± 1%  6.22µs ± 0%  -3.06%  (p=0.000 n=19+18)

Fixes #19591.
