Previously, if the device does not have hardware GPU (even though it provides software webgl), it will disable webgl backend.
Example: for this case, WebGL backend will be disabled.
This works for our users, but we want to run tests and benchmarks on WebGL backend, even if the devices only have software WebGL only (BrowserStack's windows devices). Then this PR adds a flag to disable/enable software WebGL to make it flexible.
