configs: Add all groups configuration JSON through meson.build

Map all directories and JSON files under the configs folder to
/usr/share/phosphor-led-manager.

Currently, the configs file only contains `rainier-2u` and
`rainier-4u` group configuration JSON files.

Tested: Switch to `meson` to compile ledManager and saw that
        rainier-2u and rainier-4u files are mapped to
        `/usr/share/phosphor-led-manager`.

~# ls /usr/share/phosphor-led-manager/ibm,rainier-2u
   led-group-config.json

~# ls /usr/share/phosphor-led-manager/ibm,rainier-4u
   led-group-config.json
