As described in Issue
https://github.com/KhronosGroup/OpenCL-CTS/issues/2152 we currently
check the provisional extension version supported by a vendor is the
same or older than a test specified version. However, it was discussed
in the WG that this should be a check for equality to avoid hitting
issues when a implementation tests against an older version of the CTS
using a lower extension version, with API breaking changes having
occurred since.
The tests for the command-buffer family of extensions are the only
provisional KHR tests using this versioning check, so this PR updates
all those cases to equality.
