[fabric] Extend supported counter list in syncd's FlexCounter for fabric

[ngoc-do]

New SAI version provides more counters for fabric ports. Extend the supported counter list to cover those counters.

/** SAI port stat if in FEC correctable pkts */
SAI_PORT_STAT_IF_IN_FEC_CORRECTABLE_FRAMES,

/** SAI port stat if in FEC not correctable pkts */
SAI_PORT_STAT_IF_IN_FEC_NOT_CORRECTABLE_FRAMES,

/** SAI port stat if in FEC symbol errors */
SAI_PORT_STAT_IF_IN_FEC_SYMBOL_ERRORS,

/** Fabric port stat in data units */
SAI_PORT_STAT_IF_IN_FABRIC_DATA_UNITS,

/** Fabric port stat out data units */
SAI_PORT_STAT_IF_OUT_FABRIC_DATA_UNITS,

/** Port stat in drop reasons range start */
SAI_PORT_STAT_IN_DROP_REASON_RANGE_BASE = 0x00001000,

to have this always up to date even if SAI add new counters, we could use already generated metadata for sai_port_stat_t enum, and only use enums that value is less than SAI_PORT_STAT_IN_DROP_REASON_RANGE_BASE, then we actually include all enums, even if new added
@lguohan also just wondering why we don't include in/out configured drop reasons stats here ?

@daall to check out if there is any harm to do that, i think debug counters need to be configured.
