DawnTest: only choose one adapter from those with same name and backendType 

When running Dawn end2end tests on latest Windows 10 (20H2) in a Remote
Desktop session there can be multiple adapters with same name and type,
which will cause the crash of Dawn end2end tests as the GTest framework
doesn't allow two cases having the same name.

This patch fixes this issue by only choosing one adapter from the ones
with same name and backendType in DawnTests.
