Moved portions from module i18npool, all of former i18nisolang1 library
that now is i18nlangtag. Included are languagetag, isolang and mslangid.
This i18nlangtag code is now even used by module comphelper, so
disentangling i18npool and making this an own module was needed to not
create circular module dependencies.

Always link in gb_STDLIBS, except when the library explicitly opts out
with gb_LinkTarget_disable_standard_system_libs.

There are currently 3 different mechanisms being used for frameworks,
which is of course intolerable so we invent a 4th one and standardize on
it: gb_LinkTarget_use_darwin_frameworks
(This doesn't mean using add_libs or externals was wrong, it was just
inconsistent... and i don't see an obvious benefit of using externals here)

Naming convention for gbuild methods:
- "add" is used for stuff that is logically a part of the target
(i.e. not registered at the Module, but defined in the target's makefile)
- "use" is used for stuff that is logically a different target
(i.e. it is registered at the Module, has it's own makefile, may be
in a different module than the target)
This reverts commit cd105c5ad2dc7176837a570e6507bd2ca0cd357f.
We can't use gb_Library_add_objcxxobjects here because
gb_ObjCxxObject_get_source has .mm suffix
