encoding/json/v2: remove `unknown` tag option and DiscardUnknownMembers

WARNING: This commit contains breaking changes
for those already using GOEXPERIMENT=jsonv2.

This removes support for the `unknown` tag option and
the DiscardUnknownMembers marshal option.

The `unknown` tag option semantics are a bit too subtle
even for experienced Go programmers to understand.
Remove support for it. The exact same feature (or something similar)
can be added back into a future release of json/v2.

We already support the `inline` tag option,
which can handle most cases of what someone might want to do
with unknown fields (such as preserve them).

Fixes #77271
Updates #76444

cmd/go: do not collect build information for test packages when not needed

When build information is not needed for go list output (when -export=false and Stale and StaleReason fields are not printed), the "SuppressBuildInfo" option is set to true, so that cmd/go/internal/load does not collect it (in particular VCS information, which is costly to compute).
However the option is only checked in "PackagesAndErrors", not in "TestPackagesAndErrors", so when running go list -test=true, build information is still collected, significantly increasing the duration of the command.

This CL updates TestPackagesAndErrors to check SuppressBuildInfo before calling setBuildInfo, like PackagesAndErrors does.

Fixes #77419

net: always set the servers field to defaultNS

When the field is parsed from a file, it would never
have len(servers) == 0, lets enforce that and update
test cases where we had it wrong.
