/**
 * The LdrResFallbackLangList routine builds the ordered list of languages the MUI resource loader tries for a module:
 * the requested language, its parent, the preferred UI languages, the module's ultimate fallback language,
 * then (with LDR_RES_SEARCH_RESULT_NO_RC_CONFIG) the thread locale, the user and system default locales and en-US (0x409).
 * Used by LdrpResSearchResourceMappedFile before probing alternate (.mui) modules; not exported.
 *
 * \param DllHandle The module whose MUI RC config supplies the ultimate fallback language (may be NULL to skip that step).
 * \param MappingSize The size of the DllHandle mapping, forwarded to RtlpResUltimateFallbackInfo.
 * \param LangId The requested language ID (0 = neutral; no parent step).
 * \param Flags LDR_RES_SEARCH_SKIP_MUI (0x4) stops after the requested language; LDR_RES_SEARCH_RESULT_NO_RC_CONFIG (0x80000)
 * adds the thread/default locales; LDR_LOAD_ALT_RESOURCE_LIC_FILTER (0x100000) drops LIC-restricted languages.
 * \param FallbackList Receives the fallback list.
 * \return NTSTATUS Successful or errant status (STATUS_INVALID_PARAMETER if FallbackList is NULL).
