Time drifting test cases use serial communication with the host and are unstable on CI.
Skip time-drifting test cases if SKIP_TIME_DRIFT_TESTS macro is defined.
The idea for the future is to use FPGA test shield for timing tests instead of host scripts.
Also remove `__ARM_FM` macro which in most cases was used to disable time drifting tests. In other cases replace `__ARM_FM` with `TARGET_ARM_FM` which is more suitable.
FastModels are a software simulator for Arm platform/cores.
They mean to be used as a tool for testing or early prototype stage development.
Due to the nature of software simulator can't grantee the timing accuracy like HW.
So time drifting test is skipped for software models.
Remove the direct use of the microsecond and low power ticker from
the tests. This enforces that sleep mode is properly locked when
using timers. Furthermore, this prepares the codebase for new ticker
changes which allow differing clock frequencies and timer bit widths.
