Adds Draw benchmarking support

[tig]

This PR backports some drawing benchmark stuff from

• Fixes #3761, #2886 - Draw and Layout performance issues #3798

to quantify how much improvement I'm making.

Proposed Changes/Todos

• Add support to ConsoleDriver for tests to see how often draw code is called.
• Add an All_Scenarios_Time unit test that measures how each Scenario performs w.r.t draw calls.

The results are pretty horrific.

For example.

Scenario UICatalog.Scenarios.AllViewsTester
  took 20827 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 5004 times.
    which updated the screen 5003 times.

Scenario UICatalog.Scenarios.Generic
  took 4659 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 5004 times.
    which updated the screen 5003 times.

Scenario UICatalog.Scenarios.Progress
  took 12300 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 5004 times.
    which updated the screen 5003 times.

In #3798:

Scenario UICatalog.Scenarios.AllViewsTester
  took 91 ms to run.
  called Driver.ClearContents 1 times.
  called Driver.Refresh 5003 times.
    which updated the screen 1 times.

Scenario UICatalog.Scenarios.Generic
  took 16 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 5003 times.
    which updated the screen 1 times.

Scenario UICatalog.Scenarios.Progress
  took 84 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 5003 times.
    which updated the screen 1 times.

Before:

Scenario UICatalog.Scenarios.Buttons
  took 2271 ms to run.
  called Driver.ClearContents 0 times.
  called Driver.Refresh 1004 times.
    which updated the screen 1003 times.
  called View.Draw 22044 times.

After:

Scenario UICatalog.Scenarios.Buttons
  took 82 ms to run.
  called Driver.ClearContents 1 times.
  called Driver.Refresh 1003 times.
    which updated the screen 1 times.
  called View.Draw 41 times.

These new tests expose some really bad behavior in a bunch of Views and Scenarios...

Most of which are caused by the API being unclear, which I'm fixing in #3798

Nice! this will make a huge improvement in performance! Thats like 20x less!
