tests-mbedmicro-rtos-mbed-systimer to tune ?

Description

Hi

Since 5.11.1, STM32L0, STM32L4 and STM32F7 are TICKLESS.

Then tests-mbedmicro-rtos-mbed-systimer is now executed.

Test is OK for most of targets, except few one that are failing at test case 6:

[1547654364.30][CONN][RXD] >>> Running case #6: 'Handler called once'...
mbedgt: :252::FAIL: Values Not Within Delta 2500 Expected 42000 Was 45532

mbed-os/TESTS/mbedmicro-rtos-mbed/systimer/main.cpp

Line 252 in 0b9587f

TEST_ASSERT_UINT64_WITHIN(DELAY_DELTA_US, DELAY_US, t2 - t1);

I have the feeling that delay values should be tuned ?

Here is the failed tests I got with ST CI, including the difference value "t2 - t1", which is expected to be less than 2500:

@jeromecoutant thanks for a detailed descripion. 👍 Could you run the updated code from #9416 on your targets, please? I could only test the NUCLEO_L476RG from the targets listed above; works OK now.
