This moves the creation of the Instance and Adapter discover to
environment creation. It allows programatically filtering test
parameterizations based on what is available on the system instead of
relying on what is enabled at compile time.
Because of an issue with the Vulkan validation layers, the instance and
adapters are created twice. Once in environment creation, and once on
environment set up. The Vulkan validation layers use static global
mutexes which are unsafe when Chromium's test launcher forks the
launcher process between environment creation and SetUp.

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.
