AVRO-4221: [C++] Allow using symbol visibility annotations also on non-Windows
platforms (#3600)
In GCC and clang the symbol visibility behavior of MSVC can be mirror using
`-fvisibility=hidden`.
This allows to more easily test that symbol visbility annotations work
correctly and can potentially lead to smaller binaries.
The default behavior on non-Windows platforms is not changed with this commit.
See also https://gcc.gnu.org/wiki/Visibility
Also fixes a tiny mistake where the _WIN32 macro was used to silence a MSVC
warning where the _MSC_VER macro should have been used instead.
