libcamera: ProcessManager: make ProcessManager lifetime explicitly managed

If any Process instances are destroyed after the ProcessManager is
destroyed, then a segfault will occur.

Fix this by making the lifetime of the ProcessManager explicit, and make
the CameraManager construct and deconstruct (automatically, via a member
variable) the ProcessManager.

Update the tests accordingly.
