Revert "Renamed constants in unit tests for paced sender."

Browse Source 
This reverts commit 9af0a672c277c7d062c9957acdaa641d2e1a93ac.

Reason for revert: Conflicts with reverting https://webrtc-review.googlesource.com/c/src/+/48000

Original change's description:
> Renamed constants in unit tests for paced sender.
> 
> Since paced sender no longer has an internal multiplier, the constants
> used for the unit tests were changed from supplying kTargetBitrateBps *
> kPaceMultiplier at each usage to simply using the new constant
> kPacingRateBps, simplifying the test code.
> 
> The function PacketsSentPerInterval was introduced as the value was
> computed and explained several times over in the different tests.
> 
> Bug: None
