Subject: [PATCH] Tweak .clangd to work with gcc-compiled Emacs (bug#78367)

A Gcc configuration of Emacs emits -fstrict-flex-arrays but
clangd doesn't understand that.  This causes spurious errors of
"unknown flag" that prevent analysis.  So tweak .clangd to the
nearest clang equivalent (which is very similar).

* .clangd (CompileFlags): Remove -fstrict-flex-arrays, add
-fstrict-flex-arrays=3.

(cherry picked from commit 9df2074a06fefa0b5bfe9714b45c383fa45d6650)
