refactored TPM plugins discovery, resolves #671

lift the limitation that allows plugins to only be declared from the main
`.local` customization file

from now on, spawn an ephemeral tmux server/client pair to discover plugins with
a mix of source-file -nvq and a recursive shell function

the upside of the new approach is that it respects tmux conditionals and we only
consider set -g @plugin that are really evaluated by tmux, e.g. within %if,
%elif, %else blocks

---
currently, source-file -v doesn't apply the -v flag to subsequent source-file
commands being evaluated, so we use -n and recurse ourselves

trying to (ab)use the after-set-option hook to accumulate all the evaluations of
set -g @plugin into a variable was promising, but is not immune to configuration
files that use set-(hook|option) -gu after-set-option to clear the hook, which
makes plugin discovery fail partially or even entirely
