RFR: 8312181: CDS dynamic dump crashes when verifying unlinked class from static archive [v2]

[Calvin Cheung]

> During CDS dynamic dump, VM crashes due to `assert(!k->is_shared()) failed` while linking an old class (class file version <= 49) loaded from the static archive. The fix mostly adjusts some assert statements based on static vs dynamic dumping. In `MetaspaceShared::try_link_class`, if linking of a shared class during dynamic dump has failed, the `shared_loading_failed` flag will be set to avoid linking the same class again.
> 
> Passed tiers 1 - 4 testing.
