feat: Add man page generation to Meson build

This commit implements the man page portion of step 8 of the Meson migration plan.

It adds the necessary 'meson.build' files to the 'man' and 'man/man3' directories to find 'pod2man' and generate the man pages from the '.pod' source files. The generated man pages are also installed.
