James Forshaw 359fc4a133 [Windows] Add checks for DLL loader lock.
This CL adds code to check if the current thread holds the DLL loader
lock. This code can be used to enforce the requirement that certain
parts of crashpad, such as process creation are not done during calls
to DllMain which can lead to deadlocks and crashes. Only one check is
current enforced, in client process creation, and only in debug builds.
