Taylor Blau 7ac4231b42 repack: move write_filtered_pack() out of the builtin
In a similar fashion as in previous commits, move the function
`write_filtered_pack()` out of the builtin and into its own compilation
unit.

This function is now part of the repack.h API, but implemented in its
own "repack-filtered.c" unit as it is a separate component from other
kinds of repacking operations.
