Currently more config values are being kept than necessesary. For
example, given config values for a string resource:
Config: default Value: "keep"
Config: ldrtl Value: "dedupe"
Config: ldrtl-night Value: "dedupe"
Config: land Value: "keep2"
The ldrtl-night config value will fail to be removed despite being
equivalent to the ldrtl value. This is because the value for the land
configuration is not equivalent to the ldrtl-night value. Instead of
checking that every compatible config value not related by dominance
should have quivalent values, only check sibling config values within
the dominator tree.

Locale deduping isn't straightforward, as parenting rules
change between platform versions and the selection
preference of a specific locale variant over the default
configuration lead to incorrect results at runtime.
