Add a new API to check if a given pipe is valid using DISPLAY_RUNTIME_INFO() for GVT. Update GVT to use this API instead of accessing `DISPLAY_RUNTIME_INFO->pipe_mask` directly in the `for_each_pipe` macro. Since `for_each_pipe` is defined in i915/display/intel_display.h, which also contains other macros used by gvt/display.c, we cannot drop the intel_display.h header yet. This causes a build error because `for_each_pipe` is included from both i915/display/intel_display.h and gvt/display_helpers.h. To resolve this, rename the GVT macro to `gvt_for_each_pipe` and make it call the new API. This avoids exposing display internals and prepares for display modularization. v2: - Expose API to check if pipe is valid rather than the runtime info pipe mask. (Jani) - Rename the macro to `gvt_for_each_pipe` to resolve build error. v3: - Use EXPORT_SYMBOL_NS_GPL(..., "I915_GVT"); (Jani) - Use enum pipe at call sites instead of casting in the macro.
