meson: Fix usage of overwritten pipeline variable

When iterating over enabled pipelines and IPA modules, libcamera
descends into subdirectories in a recursive manner, which involves
nested loops. Both the outer and inner loops use the same loop variable
named 'pipeline'. As the outer loop uses the variable after descending
into the inner directory, it ends up using an incorrect value. Fix it by
moving all use of the variable before the subdir() call, and add a
comment that warns about the issue to avoid reintroducing it.
