This will be very expensive in terms of area and possibly timing.
Ideally this instruction would be multi-cycle or optimised to reduce the overhead.

Changes to build with a 512-bit main data bus (with all other busses
...
still 64-bits).
Also, the top-level SoC_Top exposes a 64-bit bus still, so hopefully the
GFE configuration is unchanged.
This passes the isa_tests.

Prefer tag clearing to trapping when manipulating a sealed capability
...
This causes the behaviour of CCSeal and CSeal to diverge in non-trapping cases,
meaning an extra case is added to CapModify.
