cmd/pprof: add readline support similar to upstream
The upstream pprof implements the readline feature using
the github.com/chzyer/readline package in its pprof.go main.
It would be ideal to use the same readline support package as
the upstream for better user experience and code maintenance.
However, bringing in third-party packages requires more work
than I envisioned (e.g. clean up the vendored code to meet the
expected standard - iow don't break builders).
As a result, this change implements the similar feature
for the pprof command included in the go distribution
(cmd/pprof/pprof.go) using golang.org/x/crypto/ssh/terminal
for now.
Auto-completion is not yet supported (same in the upstream).
The feature is enabled only in linux, windows, darwin, and
only when terminal support is available.
This change brings in new vendored packages,
golang.org/x/crypto/ssh/terminal and
golang.org/x/sys/{unix,windows}.
For #14041
