wifi: ath12k: Set EMLSR support flag in MLO flags for EML-capable stations

Currently, when updating EMLSR capabilities of a multi-link (ML) station,
only the EMLSR parameters (e.g., padding delay, transition delay, and
timeout) are sent to firmware. However, firmware also requires the
EMLSR support flag to be set in the MLO flags of the peer assoc WMI
command to properly handle EML operating mode notification frames.

Set the ATH12K_WMI_FLAG_MLO_EMLSR_SUPPORT flag in the peer assoc WMI
command when the ML station is EMLSR-capable, so that the firmware can
respond to EHT EML action frames from associated stations.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
