docs/testing/citests: Expand CI testing documentation

The citests.rst now documents how to run the CI test suites locally (the
same way they are done in NuttX GitHub CI). Other pages are created for
different parts of NuttX testing.

-CI with NTFC
-============
-
-NTFC (NuttX Test Framework for Community) enables automated testing for NuttX
-across simulator, QEMU, and real hardware via serial interface. The framework
-automatically detects available applications in NuttX images and executes
-applicable tests using pytest-based test cases.
-
-The framework and official test cases are available at:
-
-- https://github.com/szafonimateusz-mi/nuttx-ntfc
-- https://github.com/szafonimateusz-mi/nuttx-testing
-
-Detailed documentation is available in the framework repository.
-
-CI migration to NTFC is in progress. Configurations currently using NTFC:
-
-- risc-v/qemu-rv: ``rv-virt/citest64``
-- risc-v/qemu-rv: ``rv-virt/citest``
-- sim/sim: ``sim/citest``
-- arm/imx6: ``sabre-6quad/citest``
-- arm64/qemu: ``qemu-armv8a/citest``
-- arm64/qemu: ``qemu-armv8a/citest_smp``
-
-NTFC exports test logs as CI artifacts. This allows test logs (including ``ostest``
-output) to be downloaded directly from the CI for all targets where the ``citest``
-configuration is enabled.
