[SV 63417] Ensure global .NOTINTERMEDIATE disables all intermediates

Fix .NOTINTERMEDIATE without prerequisites to disable intermediate
status for all targets.

* src/makeint.h: Declare extern no_intermediates.
* src/main.c: Add global definition of no_intermediates.
* src/file.c: Remove static no_intermediates to use global variable.
(remove_intermediates): Check no_intermediates.
* src/implicit.c (pattern_search): For a file found by implicit search
set file->notintermediate if no_intermediates is set.
* src/remake.c (update_file_1): Don't set file->secondary for a
pre-existing file if no_intermediates is set.  The check for
no_intermediates here is redundant, but won't hurt: keep it in case
things change so that it matters.
* tests/scripts/targets/NOTINTERMEDIATE: Fix a test.
