runtime: replace reflectcall of defers with direct call
With GOEXPERIMENT=regabidefer, all deferred functions take no
arguments and have no results (their signature is always func()).
Since the signature is fixed, we can replace all of the reflectcalls
in the defer code with direct closure calls.
For #40724.
