prima: extscan: Update extscan capabilities.

1. Update structure tpSirEXTScanCapabilitiesEvent with
   more capabilities.
2. Add structure hdd_ext_scan_context which is used for
   implementing blocking mechanism.
3. Add blocking mechanism to send extscan capabilities
   to the upper layer in same context.
4. Remove Mtrace enum TRACE_CODE_SME_RX_HDD_EXTSCAN_
   GET_CAPABILITIES to avoid multiple Mtrace messages in
   sme_EXTScanGetCapabilities
