Subject: [PATCH] XML-RPC: Pass an empty array to the `xmlrpc_call` action in
 methods that have no arguments.

This avoids an "Undefined variable" PHP notice in the `::mt_supportedMethods()` and `::mt_supportedTextFilters()` methods.

Follow-up to [50353].

Props dd32.
Reviewed by dd32, SergeyBiryukov.
Merges [50499] to the 5.7 branch.
Fixes #52524.
