Removes unbounded heap growth by capping the heap
size to 4MB and falling back to direct allocation for larger
requests.

The current BufferUpload perf test calls WaitForGPU at the end of
every step to time how long the batch of uploads took. Future tests
will want to have multiple Steps or Frames in flight to mimic real
applications that use double or triple buffering. This patch removes
WaitForGPU and adds a |maxStepsInFlight| argument which a test can
set to configure how many steps can be running on the GPU.
For the BufferUpload tests, this is still 1.

Upload perf depends on buffer size. Try small and large buffers
to ensure allocation tuning is more accurate.

This patch adds a perf test harness for Dawn and a simple test of
buffer upload performance. The test harness is based off of ANGLE's
perf tests.
Because perf tests are parameterized to support multiple test
variants, this patch also adds DawnTestWithParams and ParamGenerator
to support instantiating tests with additional parameters.
