[Mellanox] Add bitmap support for SFP error event (#7605)
#### Why I did it

Currently, SONiC use a single value to represent SFP error, however, multiple SFP errors could exist at the same time. This PR is aimed to support it

#### How I did it

Return bitmap instead of single value when a SFP event occurs
