Fixing more tests

Support LinuxMain XCTest pattern on Linux

Fix issue with relocate task

Fix other tests that require 32-bit support

Add architecture support for CppUnit tests

Add support for C++ applications to the `cpp-unit-test` plugin, by relocating the `main` symbol from the object files of the application under test. Change the `UnexportMainSymbol` to be more idiomatic and the `runTest` task to be incremental.

Move some test coverage so that it is applied to both the XCtest and C++ unit test plugins.
