Xcode: Set WMO on non-debug build configurations

Browse Source 
This patch sets the swift compilation mode to wholemodule in the xcode
generator for all non-debug build configurations at the project level.

Leaving the target build-configurations default ensures that this
default can be overridden easily by editing either the project
configuration from the build settings editor or the per-target
configuration.

When set on versions of Xcode that do not recognize the
`SWIFT_COMPILATION_MODE` setting, Xcode will include the option as a
user-defined setting, but otherwise ignore it.
