LaunchKit: launchctl as a Swift package

Based on launchctl.

This Swift package provides the LaunchKit library, a Swift library that can be used to perform the same commands supported by launchctl, but in a programmatic way without having to invoke launchctl itself.

Another target is a launchctl executable that can be built and run the same way as the built-in command on macOS.

Its main purpose is to build the launchctl command for iOS to use in a Security Research Device, since iOS doesn't have a built-in launchctl command.

Another feature is the ability to use LaunchKit in other SRD tools that have a need to interface with launchd on iOS.

Suggested entitlements (iOS / SRD)

Binaries that need to perform launchctl operations on iOS should include the same entitlements used by the sample launchctl_srd target:

<key>com.apple.private.xpc.launchd.userspace-reboot</key>
<true/>
<key>com.apple.private.xpc.persona-creator</key>
<true/>
<key>com.apple.private.xpc.service-attach</key>
<true/>
<key>com.apple.private.xpc.service-configure</key>
<true/>
<key>com.apple.private.xpc.domain-extension</key>
<true/>
<key>com.apple.private.xpc.launchd.app-server</key>
<true/>

These are defined in iOS/launchctl_srd/launchctl_srd/launchctl_srd.entitlements. Depending on the exact operations you perform, a subset may be sufficient. For example, the com.apple.private.xpc.launchd.app-server entitlement is only needed for the setenv command.
