[//gpu] Test only valid BufferUsages in MappableBuffer tests

As a step toward eliminating these tests needing to call
IsNativeGpuMemoryBufferConfigurationSupported() (which we're folding
into its one service-side production callsite), restrict the
BufferUsages that they test to the ones that are valid by platform [1].
Note: For Ozone in particular this is not statically determined;
instead, we pass the possible set of valid usages (cf. [2]) and will
migrate the tests to call
ui::OzonePlatform::GetInstance()::IsNativePixmapConfigSupported()
directly once the IsNativeGpuMemoryBufferConfigurationSupported() call
is no longer needed on any other platform.
