LOG: [clangd][test] Provide registered targets to lit tests

Summary:
We had tests in clangd (target_info.test) that got enabled only on
systems that know about x86. But they were always disabled as clangd lit config
never registered those targets.

This patch adds those targets as `$TARGET$-registered-target`
