Configure the shared LCDCAM core clock through guarded LCD and CAM LL APIs,
and unify LCD functional clock LL calls around group IDs across supported targets.

The LCD delay registers configure a delay mode (0=no delay, 1=delay on
rising edge, 2=delay on falling edge), not a tick count. Rename the LL
layer functions and parameters to reflect this, and add
lcd_ll_set_data_delay_mode for esp32s31 and esp32p4.
