mbedtls: Use LowPowerTimer/Timer for timing

Previously we used `gettimeofday()` for Mbed TLS timing, but its
implementation provided by Mbed OS is only precise to seconds. The
microsecond component of the output `struct timeval` is always set
to zero. But Mbed TLS requires millisecond precision.

To provide required timing precision, switch to use `LowPowerTicker`
or (microsecond) `Ticker`. `LowPowerTicker` is preferred as it saves
power and Mbed TLS does not require microsecond precision.

mbedtls: Add an alt implementation of timing

Implement the MBEDTLS_TIMING_ALT interface for Mbed OS. This
implementation is sufficient to run the Mbed TLS benchmarking
application.
