[amlogic][clock] Add clkctl command line utility to measure clocks

Changes in this CL
- Memcpy the static array before creating fbl::Array so
static array doesn't get destroyed when fbl::Array gets destroyed.
- Added new IOCTL to get the count of clocks in the clock_table.
- Added a command line utility to measure clocks.
- Renamed the folder because of possibility of overlapping .so's
generated due to an existing bug in the build system

Test: manual testing on Astro
