time-keeping: keep timestamp in multi, always update

Always use curlx_now() when calling Curl_pgrs_now(data). Tests with the
"manual" updates to now proved differ more then 100ms in parallel testing.

Add `curlx_nowp()` to set current time into a struct curltime.
Add `curlx_ptimediff_ms() and friends, passing pointers.

Update documentation.
