aiongg a6428d3dfb Build each crate's integration tests as one binary ...

Every tests/*.rs file is its own executable that links the whole crate
graph. Move each crate's test files into tests/it/ as modules of one
tests/it/main.rs; helper modules under tests/common move with them.

These keep their own binary (own process):
- engine panic_hunt: a process-wide panic hook counts every panic.
- engine text_gamma: changes the process-wide text gamma.
- engine smart_filter_stages, mask_cache_purge: assert on global caches.
- codecs pnm_peak_memory: reads the process's peak RSS.
- photocraft mac_menu_appkit: harness = false.
