The base nir options were assuming all bit sizes were supported at shader model 6.2. Multiple callers were then changing properties based on actual support. Standardize behavior by providing the majority of things that can impact nir options when getting them. Some callers (e.g. meta blit shaders or libclc) don't bother, because they are known to have contents that are unaffected by these options. Other callers might munge more properties afterwards, but this minimizes that. Note that lower_helper_invocation was incorrectly being turned off for SM6.6+ by some callers, despite load_helper_invocation being unimplemented by the backend.
