selftests: drv-net: rss_ctx: add tests for RSS contexts

Add a few tests exercising RSS context API.
In addition to basic sanity checks, tests add RSS contexts,
n-tuple rule to direct traffic to them (based on dst port),
and qstats to make sure traffic landed where we expected.

v2 adds a test for removing contexts out of order. When testing
bnxt - either the new test or running more tests after the overlap
test makes the device act strangely. To the point where it may start
giving out ntuple IDs of 0 for all rules..
