Corentin Wallez 30ec4fc626 Fixes to be able to build Dawn inside Skia
Add a dawn_has_build override similarly to angle_has_build that makes
Dawn not depend on Chromium //build if it can avoid it. (this was
previously used for mac_sdk.gni).

Only load the Vulkan Validation Layers' gni if it is enable via
dawn_enable_vulkan_validation_layers.

Fix a GN build warning where the source of dawn_components would be
built twice: for example libdawn_native.MetalBackend.o would be built
once for libdawn_native static and once for libdawn_native shared. Fix
this by making libdawn_native as a static library libdawn_native_static.
