dlopen-note: move all dlopen notes to dlopen-note.h

Browse Source 
This also switches all these notes to be defined via SD_ELF_NOTE_DLOPEN_ANCHORED().
Consequently, any notes added within unreachable or unused functions will be
automatically garbage-collected by the linker (--gc-sections) instead of
bloating the final binary.

E.g. unused p11-kit library dependency is now dropped from
systemd-repart.standalone binary.

Before:
```
$ systemd-analyze dlopen-metadata build/systemd-repart.standalone
