GYP: Make the ARM simulator build with GYP again

Updated the armu.gypi to set values for variables which does not have a default. These variables was recently added to v8.gyp.

Moved the what will be shared between building the v8 library and the cctests to a separate include file. For now this file is currently only used by cctest.gyp. the reason is that the cctests are not just using the API but also internal functions so the C++ defines and optons needs to be the same when compiling the cctests files as when compiling the v8 library files.
