### Contribution description

While working on some of my STM32 boards addition, I noticed the timer configuration were very often the same, certainly due to copy-paste. Some uses TIM2, some uses TIM5.

This PR is introducing 2 new common STM32 timer configurations: one with TIM2, which is adapted for several families (L0, L1 and L4) and one with TIM5, mostly used by F4 boards.

I tried to adapt all boards with these configuration.

The results is a lot of duplicated code in peripheral configurations being removed.

### Testing procedure

- Verify xtimer test applications still works
- A green Murdock should also be a good indicator
- Verify no obvious mistake is done in the code changes

<!--
Details steps to test your contribution:
- which test/example to compile for which board and is there a 'test' command
- how to know that it was not working/available in master
- the expected success test output
