Locate per-dist and per-module shared files

The intent of FileShareDir is to provide a companion to ClassInspector and FileHomeDir, modules that take a process that is well-known by advanced Perl developers but gets a little tricky, and make it more available to the larger Perl community.

Quite often you want or need your Perl module CPAN or otherwise to have access to a large amount of read-only data that is stored on the file-system at run-time.

On a Linux-like system, this would be in a place such as /usr/share, however Perl runs on a wide variety of different systems, and so the use of any one location is unreliable.

Perl provides a little-known method for doing this, but almost nobody is aware that it exists. As a result, module authors often go through some very strange ways to make the data available to their code.
