[Ada] ada_unpack_from_contents: Error if target buffer not large enough

This adds a guard that the size of the "unpacked" buffer is large enough
to contain at least BIT_SIZE bits.  If not, report an error.  This is to
guard this routine from doing buffer overflows when called incorrectly.

gdb/ChangeLog:

        * ada-lang.c (ada_unpack_from_contents): Add guard that unpacked
        is large enough for BIT_SIZE.  Update function comment.
