drm/msm/sde: use intf te in sde encoder for sde 5.0.0

sde encoder module depends on SDE_INTF_TE flag to route
the te configuration to either hw_intf or hw_pp module.
This change enables SDE_INTF_TE flag for sde 5.0.0 and
also implements the te ops routing call based on this flag.
This change configures vsync selection for intf te.
