Remove duplicate com.sun.star.i18n.IndexEntrySupplier_ja_phonetic_* impls

Ever since 95823ae83c8c13c5c10c5084e2a90549ff2eb25e "#95565#add new phonetic
entry for CJK index modules", "com.sun.star.i18n.IndexEntrySupplier_ja_phonetic
(alphanumeric first)" was using the same implementation as
"com.sun.star.i18n.IndexEntrySupplier_ja_phonetic (alphanumeric first) (grouped
by syllable)", and "com.sun.star.i18n.IndexEntrySupplier_ja_phonetic
(alphanumeric last)" was using the same implementation as
"com.sun.star.i18n.IndexEntrySupplier_ja_phonetic (alphanumeric last) (grouped
by syllable)".  But there appears to be no evidence that those implementation
names "com.sun.star.i18n.IndexEntrySupplier_ja_phonetic (alphanumeric first)"
and "com.sun.star.i18n.IndexEntrySupplier_ja_phonetic  (alphanumeric last)" are
actually used anywhere (see also c9b6bf655e6de50c55629b4805399932c90a3b30 "Add
some tests for (Japanese) i18n::IndexEntrySupplier behavior").

And a problem with the current setup is that instantiation those two
implementation names will return implementations whose getImplementationName()
does not match those implementation names (but rather returns
"com.sun.star.i18n.IndexEntrySupplier_ja_phonetic (alphanumeric first) (grouped
by syllable)" and "com.sun.star.i18n.IndexEntrySupplier_ja_phonetic
(alphanumeric last) (grouped by syllable)", resp.)---which is something that
would create failures with an improved CppunitTest_services.
