feat(permissions): add "--deny-*" flags (#19070)

This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.

These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.

Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.

Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.

Closes #18804.
