nvgpu: userspace: bundle mocked IO space definitions into library

At present each nvgpu test unit defines its own mocked IO space. This is used to
intialize the qnx/posix IO framework. This results in unwanted redefinitions,
bloating of the binary. This patch creates a shared library which contains all
the mocked IO space definitions and it exports a function which enable units to
query, get access to the mocked IO space.
