Add hasScope as a valid SpEL expression to PreAuthorize, etc.

[kistlers]

Expected Behavior

In a similar fashion to the added hasScope for authorization rules (added with #13754), I would like to use hasScope(scope) in SpEL expressions in @PreAuthorize, i.e.:

@PreAuthorize("hasScope('read'")

Current Behavior

This can already be achieved using hasAuthority:

@PreAuthorize("hasAuthority('SCOPE_read'")

Evidently, not a big issue. But I'd like to add that hasRole also exists:

private String defaultRolePrefix = "ROLE_";

@Override
public final boolean hasAnyRole(String... roles) {
    return hasAnyAuthorityName(this.defaultRolePrefix, roles);
}
