Remove ModuleInfo#isHidden Usage from the source code.

ModuleInfo#isHidden is used for getting hidden module status from
ModuleMetadata package (Mainline). It was set to hide Mainline modules'
Apk to show in the Settings UI and this has caused the issue as it
disallowed the user to toggle permissions where it was needed. Thus, we
decided to deprecate the usage of ModuleInfo#isHidden (see
go/aml-hidden-modules-permissions).
