[fuchsia] Add headers containing extra vulkan definitions.

The Fuchsia platforms relies on a number of Vulkan extensions
that have not been upstreamed to Khronos yet, and thus are not
part of the official Vulkan headers (i.e. <vulkan/vulkan.h>).

This CL adds a new header under src/common/ that contains these
declarations, extracted from the Fuchsia source tree, and ensures
they are included automatically from <common/vulkan_platform.h>

This is necessary to support certain features when building
Dawn on Fuchsia.

IMPORTANT NOTE: Some of the things declared in this header will
change once everything is upstreamed, which will require updating
the source code using them. For example,

  VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TEMP_ZIRCON_EVENT_BIT_FUCHSIA

Will likely be renamed officially as:

  VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT

And will be assigned a new value by Khronos.
