This commit adds a new apex override for the Thread HAL which uses a
simulation RCP. This will be used by goldfish emulators.
Note that this can't be defined in /device/generic/goldfish because of
below error:

com.android.hardware.threadnetwork is a new VAPEX containing
threadnetwork HAL. It also includes ot-rcp.

The current fuzz testing comunicates with the Thread radio chip
simulation program `ot-rcp`. The 'ot-rcp' is not installed by all
devices, which causes the fuzz testing program is unable to find
the program '/vendor/bin/ot-rcp'.
This commit enables the HAL to talk to the '/dev/null' to avoid
'/vendor/bin/ot-rcp' not being found.

Test: Run the fuzz test on cuttlefish

This commit enables the Thread Network HAL to support the Spinel
SPI interface.
Bug: 277286756
Test: Build and run otbr-agent on the emulator.
