QCamera3: Fix Easel HDR+ mode after flush

Reset mFirstPreviewIntentSeen in flush if HAL intends to restart the
channel after flush. Without this, Easel HDR+ mode will not be
enabled after flush, unless a new session is configured.

Create a HDR+ client listener handling thread to avoid handling
HDR+ client callbacks in HAL in the callback thread, which may lead
to deadlocks.

Test: Camera CTS
