macOS: fix target detection more
Now SCDynamicStoreCopyProxies is called (and the required frameworks are
linked in) on all versions of macOS and only on macOS. Fixes crash due
to undefined symbol when built with the macOS 10.11 SDK or earlier.

CURL_OSX_CALL_COPYPROXIES is renamed to CURL_MACOS_CALL_COPYPROXIES and
is now only defined when SCDynamicStoreCopyProxies will actually be
called. Previously, it was defined when ENABLE_IPV6 was not defined but
SCDynamicStoreCopyProxies is not called in that case.

TARGET_OS_OSX is only defined in the macOS 10.12 SDK and later and only
when dynamic targets are enabled. TARGET_OS_MAC is always defined but
means any Mac OS or derivative including macOS, iOS, tvOS, and watchOS.
TARGET_OS_IPHONE means any Darwin OS other than macOS.

Fixes #11502
Closes #11516
