STM32: enable TICKLESS

[jeromecoutant]

Description

I propose to enable TICKLESS for STM32 targets which are using LPTIM feature for LPTICKER.

This PR also update the LPTICKER_DELAY_TICKS to 4 according to #8783

NB: note that it is still possible to remove this tickless feature in you mbed_app.json file if needed/wanted:
ex:
"target_overrides": {
"NUCLEO_L476RG": {
"target.macros_remove": ["MBED_TICKLESS"]
},

LGTM! Will provide results for these families with tickless against Pelion tests soon.

Can you review test logs for NUCLEO_F207ZG ? There are failures for all toolchains

no... I don't have access to logs

The url above "Build artifacts" should be accessible:

Here's the link again:

Browse to the tests, the target NUCLEO_F207ZG and you should see the logs there. If not, this is a bug that we should fix, please let us know

OK

• F207 should not be affected by this PR

• I checked 3 failed tests, and it seems they are not started... I don't understand why uart sync has failed.
