VulkanContextProvider is created before GrShaderCache and so cache
wasn't pass to Skia via GrContextOptions.

This CL defers init of GrContext in VulkanInProcessContextProvider to
SharedContextState::InitializeGrContext to mitigate this.

Use of cache itself is under feature flag for metrics comparison and
a kill switch purpose.
