Subject: [PATCH] fix(core): move drops_unsupported_params into core_helpers on
 lts/1.108.x

Prerequisite of #48931 on lts/1.108.x, hand-ported from the core_helpers move in b51b9b7d43d (#47347), which the line does not carry. tool_fields imports the helper from core_helpers, and the responses bridge now imports it from there too.
