permission: add unique warning codes

[davidje13]

Adds unique warning codes of the form PERM0000 for all permissions-related SecurityWarnings, so that they can be individually (and minimally) silenced if required, e.g. --disable-warning=PERM0002. See #59818 (comment) for an example use-case.

There isn't much of an existing pattern for warning codes, except DEP0000 for deprecations, so this follows that convention. There are currently 2 other places which generate SecurityWarnings which should perhaps be given unique codes as well (something for a separate PR I think)

Fixes: #59818
