test: lorawanstack: Use valid message type ...

We previously made up an invalid message type, which was roughly
`MCPS_MULTICAST | 0x40`. This causes an MBED_ASSERT failure in the
handle_rx function, as it uses an assert to validate the message type
passed to it (in convert_to_msg_flag()). Use the valid message type
MCPS_MULTICAST instead in the handle_rx unit test.

unittests: Test_LoRaWANTimer.start: Fix test failure ...

We weren't initialising the mocks correctly, so an MBED_ASSERT failed in
`LoRaWANTimer::start` because the "timer_id" was not set.

cmake: Avoid linking to gcov ...

Use the `--coverage` option instead of manually linking to gcov, as some
host platforms (like macOS, FreeBSD) don't have gcov by default and use
an llvm equivalent instead.

cmake: Remove trailing whitespace ...

Remove trailing whitespace from lorawantimer's CMakeLists.txt.

CMake: Limit the mbed-fakes-ble to required dependency mock

CMake: Move ble fakes into FEATURE_BLE double dir ...

Previously ble fakes as part of UNITTESTS/fakes, this PR moves
ble fakes to FEATURE_BLE double directory to make ble stubs
to be self-contained.

Remove mbed-headers-connectivity ...

Moved all the headers out of mbed-headers-connectivity, and these changes remove
that headers lib reference from lorawan and cellular unit tests

CMake: Create mbed-headers-ble library ...

Previously ble headers are part of mbed-headers-connectivity, this PR
moves ble headers into new mbed-headers-ble to make ble stubs to be
more self-contained and improves the composition of the library.

Unittests: Make netsocket test header dependencies explicit ...

The CMake target `mbed-headers` brings in all
headers, and we are gradually moving away from it and explicitly use
only headers needed by each unit test.

Unittests: Replace files with stubs in netsocket unit tests ...

Some netsocket unit tests depend on nanostack-libservice library, but
should use stubs instead of including the source files. We remove the
source files and link to mbed-stubs-nanostack-libservice.

Unittests: Clean up unused sources from netsocket ...

Some source files included when building netsocket unit tests with CMake
were determined to be unused by removing the files from target_sources()
and verifying that the tests still built and ran successfully. These
files have been removed from CMake builds.

CMake: Limit cellular device cmake to use mocks/sources what it depends ...

CMake: Limit the mbed-stubs-nanostack-libservice to required dependency mocks

CMake: Add mbed-headers-nanostack-libservice library ...

Previously all nanostack libservice headers part of
mbed-headers-connectivity. This PR moves all the nanostack
libservice headers into newly added mbed-headers-nanostack-libraries.
This makes the nanostack libservice stubs more self-contained and
improves the composition of the library.

CMake: Move nanostack libservice stubs to the connectivity/libraries dir ...

Move the connectivity nanostack-libservice stubs into the connectivity/libraries
directory where the nanostack libservice component present as nanostack
libservice source copied from the external repo. So we can avoid duplicating
the mbed-os source tree in a central UNITTESTS folder.
