[tests-only][full-ci]Refactor share permission related scenario in coreApiSharePublicLink2

[amrita-shrestha]

Description

As ownclouders decided #4052 (comment)

It was officially agreed that we do act differently than oc10. If the permissions requested by the client are not applicable we return an error (unlike oc10 which will downgrade permissions to 1)
Share permission behavior is different in oc10 and ocis.

• refactor public link share permission related scenario
• remove @skipOnOcis tagged scenario

FILES
