cocci: split off "--all-includes" from SPATCH_FLAGS

Browse Source 
Per the rationale in 7b63ea57500 (Makefile: remove mandatory "spatch"
arguments from SPATCH_FLAGS, 2022-07-05) we have certain flags that
are truly mandatory, such as "--sp-file" and "--patch .". The
"--all-includes" flag is also critical, but per [1] we might want to
ad-hoc tweak it occasionally for testing or one-offs.

But being unable to set e.g. SPATCH_FLAGS="--verbose-parsing" without
breaking how our "spatch" works isn't ideal, i.e. before this we'd
need to know about the default include flags, and specify:
SPATCH_FLAGS="--all-includes --verbose-parsing".

If we were then to change the default include flag (e.g. to
"--recursive-includes") in the future any such one-off commands would
need to be correspondingly updated.

Let's instead leave the SPATCH_FLAGS for the user, while creating a
new SPATCH_INCLUDE_FLAGS to allow for ad-hoc testing of the include
strategy itself.
