[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.

[compiler-rt][Darwin] Refactor minimum deployment target substitutions

* Support macOS 11+ version scheme
* Standardize substitution name `%min_deployment_target=x.y`
* Remove unneeded error cases (the input version is hard-coded)
* Specify version as tuple instead of string; no need to parse it

These changes should also facilitate a future addition of a substitution
that expands to "set deployment target to current target version"
(https://reviews.llvm.org/D70151).
