Remove renderable flag from texture createLazyProxy.

Besides some tests, we always set the renderable flag to kNo for this
function. No need to keep supporting a code path we don't actually use.
Tests that use to pass in kYes here have been converted to calling
createLazyRenderTargetProxy instead.
