[iOS] Use finer-grained media services when available

https://bugs.webkit.org/show_bug.cgi?id=249033
<rdar://100435873>

Reviewed by Per Arne Vollan.

Use more specific mach services for media features on platforms that support them.
This will allow us to narrow the scope to only those endpoints required for
web-related media tasks.

No change in behavior.
