binder: freeze multiple contexts
binder freeze stops at the first context found for any pid, but
multiple ones are possible with the result that a process might end
up with inconsistent context states after freezing or unfreezing its
binder.
Freeze or unfreeze all contexts in a process upon a BINDER_FREEZE
ioctl.
Bug: 176996063
Test: verified that all contexts in a specific process with multiple
binders are frozen or unfrozen.
