[PATCH 10/27] libcamera: software_isp: Start the ISP thread in configure

[Bryan O'Donoghue]

OpenGL is not thread-safe and in fact associates invisible handles with the
threadid of the calling context.

As a result we need to make configure() and process() in SoftISP execute on
the same thread.

Move start thread into configure() as a first step towards this.
