Generate cpanfile with feature information

[CyberShadow]

Details

Loading feature information from CPAN::Meta is currently not supported by Module::CPANFile, so do this by hand for now.

Fixes cpanm not installing dependencies for enabled features (as it prefers reading the cpanfile over MYMETA.*).

Additional info

• Upstream bug: mymeta-cpanfile should convert optional features miyagawa/cpanfile#55

Test Plan

It may make sense to add some automation to verify that the generated cpanfile matches the one in version control. Maybe something like this:

diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml
index d0839a88a..a3cf15eb7 100644
--- a/.github/workflows/release.yml

With this applied it looks like some dependencies that checksetup.pl thinks are required aren't being installed.
