Auto merge of #87619 - 12101111:fix-native_link_modifiers_bundle, r=petrochenkov

Fix feature gate checking of static-nobundle and native_link_modifiers

Feature native_link_modifiers_bundle don't need feature static-nobundle
to work.

Also check the feature gates when using native_link_modifiers from command line options. Current nighly compiler don't check those feature gate.
