feat: @target intrinsic

[Chriscbr]

As a more convenient alternative to importing the util module and using util.env("WING_TARGET") to obtain the current cloud target, this PR adds a dedicated intrinsic function @target which does the same thing.

In terms of design, the motivation of the new syntax is to make it clear that this kind of pattern (where you alter application logic or configuration based on the compilation target string) is an intended pattern in Wing and something handy for building abstractions around, not a hacky workaround.

Existing code that uses the WING_TARGET environment variable will continue to work (no current plans to deprecate it).
