In a future CL we will make use of InitializeContext2 which can produce
contexts of varying sizes - this makes the existing use of a union for
wow/x64 contexts no longer feasible.
The context union in process_reader_win is replaced with a (moveable,
copyable) helper struct which currently only knows how to allocate
the replaced WOW or CONTEXT sized unions.
As this field is no longer a member of the Thread struct it cannot
be passed into other functions as a reference, so instead a pointer
is used in these functions.
