[Cocoa] Stop using non-prefixed vDSP functions in 32-bit builds

https://bugs.webkit.org/show_bug.cgi?id=182898
<rdar://problem/37195079>

Reviewed by Tim Horton.

There's no need to use non-prefixed vDSP function aliases on 32-bit builds.
The vDSP-prefixed versions are available on all Cocoa platforms we currently support.
