Add infoplist API + Info.plist embedding in Apple OS console apps

[noresources]

What does this PR do?

The infoplist API adds a more explicit way to set the App bundle info in Xcode.
gmake, codelite and ninja generators now supports Info.plist by adding Apple toolchain specific flags provided by the new toolset.getSections() function.

The gcc.getSections() allows other generator to embed the Info.plist in the binary.
This will allow command line tools to have bundle informations and security entitlements.

How does this PR change Premake's behavior?

If infoplist "file" is set in premake script. The automatic detection of .plist in xcode will be ignored.

Anything else we should know?

In the future, toolset.getSections() may be used to embed any file into the binary
by adding a new dedicated API or by handling

filter {"*.bin"}
	buildaction "Embed"
	```
