Parallelize locale merging in mix gettext.merge (#436)

Benchmark on a 16-locale / 11-domain Phoenix app (160 PO files, ~4,700
msgids, Elixir 1.20.1 / OTP 29, Apple Silicon):

    mix gettext.merge priv/gettext --no-fuzzy

    before: 9.4s wall (55% CPU)
    after:  1.9-2.4s wall (341-381% CPU)

~4.9x speedup with byte-identical output files (clean git status over
committed PO state after both runs). The win scales with locale count.
