refactor: use base::NoDestructor instead of base::LazyInstance (#40947)

* refactor: use NoDestructor for g_io_thread_application_locale

* refactor: use NoDestructor for ExtensionActionAPI::GetFactoryInstance()

* refactor: use NoDestructor for ElectronExtensionsClient::GetPermissionMessageProvider()

* refactor: use NoDestructor for feat_add_support_for_overriding_the_base_spellchecker_download_url.patch

* chore: remove unused #include

* fixup! refactor: use NoDestructor for ElectronExtensionsClient::GetPermissionMessageProvider()

make sure instance is static

* chore: remove unused #include "base/lazy_instance.h"
