Embed compatibility manifest into all *.exe files

This CL introduces an automated and centralized way to embed
compatibility manifest into all *.exe files. With this CL,
a potential risk of behavioural inconsistency between
production binaries and unit test binaries is resolved by
enforcing the same compatibility context.

This CL uses 'target_conditions' feature of gyp to inject
manifest settings into each executable target. One tricky
part is that some executables such as setup.exe and
mini_installer.exe require external manifest file instead of
embedded one when component build is enabled. 
See http://crbug.com/127233 for this.

You can override the gyp variable
'win_exe_compatibility_manifest' locally for a given
executable target to embed a custom compatibility manifest.
