[PATCH v2025.09.y 51/58] Makefile: include scripts/ in compile_commands.json

[Ahmad Fatoum]

From: Jonas Rebmann <jre at pengutronix.de>

Although in many cases, C files in scripts/ would, because they rely on
the host toolchain and no unusual compiler flags, work fine in clangd
without a compile commands database, the (typically cross) compile
commands of the first entry in compile_commands.json are applied as
defaults once generated via `make compile_commands.json`.

As valid .cmd files are already present in scripts/ and
gen_compile_commands.py supports reading all cmd files in a subtree
recursively, simply add scripts to the gen_compile_commands.py
invocation. All enabled code in scripts/ is now properly covered by
compile_commands.json

(cherry picked from commit 8292499af8e917ed414ec57c36369068cfb98e13)
