- Adds system utility to get the module directory for dawn native.
- Updates Vulkan backend to use the module directory to find loader.
- Test ran on NVIDIA GTX 1660 here: https://chromium-swarm.appspot.com/task?id=576d77991add7c10.

Found while investigating Swiftshader support. Some Vulkan loaders
fail to create an instance if VK_ICD_FILENAMES is empty string
rather than entirely absent. It was set to empty string because
Dawn did not distinguish between nonexistent environment variables
and the empty string. This CL adds distinguishing between the two,
including tests for the behavior.

Projects using Dawn that are compiled with Emscripten may use some
of our common headers and utilities. ex.) creating a ShaderModule
from SPIR-V. Add handling for __EMSCRIPTEN__ to Platform.h so
compiling to WASM works.
Also, implement GetExecutablePath on Emscripten as unreachable.
This is only ever used to search native paths in the Vulkan backend.

In the Vulkan backend, we only need to set VK_LAYER_PATH and
VK_ICD_FILENAMES while we're gathering the device information. After
this, we should unset the environment variables or they will persist
and affect loading Vulkan again (from Dawn or another client) in the
future.

Deploy self-built Vulkan validation layers instead of system installed
one. And it will reuse third_party/angle's Vulkan validation layers if
building with chromium.
