Upstream Apple's direct-to-Metal backend: compile translator. This change is meant to merge the translator changes from Apple's direct-to-Metal backend. Taken from Kyle Piddington's CL: https://chromium-review.googlesource.com/c/angle/angle/+/2857366/ The goal of this CL is to merge the translator code in a state that compiles, but not to switch the Metal backend over to use this translator backend yet. Bug: angleproject:5505 Change-Id: I68a6354604498cd5fd1eb96c13fc56f3b38f2bd0 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2897536 Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Commit-Queue: Jonah Ryan-Davis <jonahr@google.com>

// RemoveInactiveInterfaceVariables.h:
// Drop shader interface variable declarations for those that are inactive. This step needs to be
// done after CollectVariables. This avoids having to emulate them (e.g. atomic counters for
// Vulkan) or remove them in glslang wrapper (again, for Vulkan).
//
// Shouldn't be run for the GL backend, as it queries shader interface variables from GL itself,
// instead of relying on what was gathered during CollectVariables.
