Use 'NonEmpty' for the fields in an 'HsProjection' (#20389)
T12545 is very inconsistently affected by this change for some reason.
There is a decrease in allocations on most configurations, but
an increase on validate-x86_64-linux-deb9-unreg-hadrian. Accepting it
as it seems unrelated to this patch.
Metric Decrease:
T12545
Metric Increase:
