Add following host fixes related to EMLSR association.
1) Use phy cap get macro to extract EMLSR hw mode id.
2) Add logic to send EMLSR cap flag during vdev start.
3) Add logic to copy EML caps from assoc link common
info subfield to MLO peer assoc struct in order to
share EML caps to FW on both links via peer assoc.
4) Add checks to update EMLSR cap flag only if both
STA and AP support and advertise EMLSR mode.
5) Send EMLMR support flag along with EMLSR support
flag to FW as part of vdev set IE cmd for roaming
scenarios. Also, update common info length when EML
caps are present.
