postprocess: fix pp_filters visibility and enable LTO in CI
The main reason for this MR is fixing the situation when the linker drops the declaration of pp_filters
because of using aggressive LTO optimizations.
Two commits:
-
Move the definition of pp_filters into
**/pp_init.c
. -
Enable CI to test with LTO enabled.
Fixes: #7881 (closed)
