  [ELF] Keep st_type for symbol assignment

PR46970: for `alias = aliasee`, the alias can be used in relocation processing
and on ARM st_type does affect Thumb interworking. It is thus desirable for the
alias to get the same st_type.

Note that the st_size field should not be inherited because some tools use
st_size=0 as a heuristic to detect aliases. Retaining st_size can thwart such
heuristics and cause aliases to be preferred over the original symbols.

(cherry picked from commit 9670029b6b302c75bb373fb1814f4e02790c4da8)
The test symbol-assign-type.s was rewritten to not depend on 'split-file'.
