  Vulkan: Enable EGL_ANDROID_recordable for EGL configs on SwiftShader
  
  There does not seem to be a way to query the Gralloc and Vulkan
  drivers for recordable support so keep this as a narrow hack
  restricted to SwiftShader.
  
  Bug: b/181163023
  Test: `cts -m CtsMediaTestCases` on Cuttlefish w/ SwANGLE
