EIP-3076 tests - complete database (#4958)

* EIP-3076 interchange tests: Add `should_succeed_complete` boolean.

This new added `should_succeed_complete` boolean means the test should succeed using
complete anti-slashing DB, while the untouched `should_succeed` boolean is
still implicitely reserved for minimal anti-slashing DB.

Note:
This commit only adds the new `should_succeed_complete` boolean, and copy the value from
`should_succeed` without any meaning regarding the value this boolean should
take.

* `TestEIP3076SpecTests`: Modify two tests

Those two tests are modified in a way they both comply with minimal AND
complete anti-slashing DB.

* Disallow false positives and differentiate more minimal vs complete cases

* Fix my own typos

* Update to v5.3.0 tag
