De-duping of configurations with locales was disabled previously since
there is not a good way to dedupe locales in a forwards compatible way
(change SHA: e38567480b).
In b/171892595, since every locale is a root in the dominator tree,
configs that do not specify locale qualifiers are dominated by the
default config and their values are checked for compatiblity with the
locale config values.
b/171892595 took a while to detect because, this is only an issue at
runtime when a resource has one config containing mnc/mcc without a
locale, one config containing a locale, and the values for the configs
differ. This is because mcc/mnc is the only qualifier with a greater
precedence than locale.
Make configurations with mcc/mnc and mcc unable to be dominated until
locale deduping is fixed.

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.
