previously, performance measurement based on platform clock, source
clock is 38.4mhz, for better align with CPC calculation, change
clock to dsp clock, this will be done through enable config:
CONFIG_TIMING_FUNCTIONS, and this config only be used with perf_cnt
header file, so this change only have impact on performance build.

Heap memory profiling is based on runtime zephyr API.
It will print out each memory allocation with allocated bytes
and free bytes, display as below:
zephyr: heap allocatd: 22c0 free: 152a90 max allocated: 1000

PERFORMANCE_COUNTERS_RUN_AVERAGE is not an independent macro,
it depend on: PERFORMANCE_COUNTERS, so it is duplicated,
remove this macro and use one macro to control this module,
also reduced unnecessary profiling log print.

After add this file, with -o app/perf_overlay.conf in build command
line, profiling functionality will be enabled and mtrace/sof log will
have performance data for further analysis.
