Vulkan: Add support for using dedicated allocation when importing images.

This is required to make importing images work on some systems. The
ideal version would be detecting whether dedicated allocations are
needed as Vulkan provides reflection for that. However this reflection
doesn't work on Nvidia, so instead Dawn requires a
NeedsDedicatedAllocation enum on import that's Yes/No/Detect so the
application can force use of a specific code path.

Support for this enum and toggling dedicated allocations on/off is added
for all external memory service implementations.

Vulkan image wrapping tests are modified to add test parameters so that
the Yes/No/Detect code paths are covered by tests.

This is technically post-V1 work, but gl_tests in Chromium fail on
Nvidia workstations without this fix, which makes it hard to debug other
issues.
