Apply asm redirections in wchar.h before first use
Similar to d0fa09a770, but for wchar.h. Fixes [BZ #27087] by applying all long double related asm redirections before using functions in bits/wchar2.h. Moves the function declarations from wcsmbs/bits/wchar2.h to a new file wcsmbs/bits/wchar2-decl.h that will be included first in wcsmbs/wchar.h. Tested with build-many-glibcs.py. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> (cherry picked from commit c7509d49c4e8fa494120c5ead21338559dad16f5)
