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.

This updates the content of third_party/khronos/vulkan
to match the upstream v1.1.115 headers.
+ update third_party:vulkan_headers to define the VK_USE_PLATFORM_XXX
macros directly, since this better matches the upstream BUILD.gn
file behaviour.
NOTE: A better patch would use a DEPS entry to get the Vulkan
headers. That's exactly what [1] does, but fails to
integrate with Chromium due to its messy situation
regarding the use of vulkan headers.
Once the Chromium situation is fixed, it will be possible
to remove third_party/khronos/vulkan entirely and rely
on a DEPS entry.

This completely removes the dependency on glad by generating the GL
headers from gl.xml directly.
This requires adding khrplatform.h so all Khronos dependencies are
gathered in third_party/khronos.
Also removes a stray CMakeLists.txt that was still hanging out.
