Work around api-extractor import bug

The import expression for the ETW trace types breaks API extractor; it
outputs a named import for a non-existent name in the module rather than
emitting a default import. For now, redeclare the type locally and then
use a conditional type to verify that what we have is compatible with
the upstream type when type checking locally.
