Subject: [PATCH] fix(crashpad): capture a real CONTEXT for the immediate dump

LPCONTEXT was zero-initialised to null, passed to GetThreadContext and
then dereferenced, guaranteeing a crash in the crash path. Capture the
calling thread's context with RtlCaptureContext and pass it to
DumpWithoutCrash.
