QCamera2: HAL3: Add support for histogram

Add vendor tags for histogram related control/metadata:
- static: number of bins supported
- control/dynamic: number of bins
- control/dynamic: histogram enable/disable
- dynamic: histogram stats

Remove the unnecessary memcpy of histogram data.

Test: histogram test case in PTS test.
