doc: release-notes-3.7: Document removal of old gsm modules

Browse source 
The GSM_PPP device driver and its direct dependencies, UART_MUX
and GSM_MUX have been removed. The net/gsm_modem sample has been
removed and the net/cloud/tagoio and net/mgmt/updatehub samples
have been updated to align with this change.

This commit documents all above.

``west build``. This snippet sets the :kconfig:option:`CONFIG_BT_ZEPHYR_NUS_AUTO_START_BLUETOOTH`
which allows non-Bluetooth samples that use the UART APIs to run without modifications
(e.g: Console and Logging examples).
* Removed ``GSM_PPP`` specific configuration overlays from samples ``net/cloud/tagoio`` and
``net/mgmt/updatehub``. The ``GSM_PPP`` device driver has been deprecated and removed. The new
``MODEM_CELLULAR`` device driver which replaces it uses the native networking stack and ``PM``
subsystem, which like ethernet, requires no application specific actions to set up networking.
* Removed ``net/gsm_modem`` sample as the ``GSM_PPP`` device driver it depended on has been
deprecated and removed. The sample has been replaced by the sample ``net/cellular_modem``
based on the ``MODEM_CELLULAR`` device driver.
