qcacmn: Add qdf api support for mtrace logging

Currently mtrace messages are getting recorded in circular
queue but are not getting used for DIAG Infrastructure.
Add support to print the mtrace messages on DIAG infrastructure in
format such that there will be two 32 bit fields printed on the
logs. These two fields will be constructed as explained below:
1. First field will be constructed using below bit positions:
   a. Bit 0 – 14 ( 15 Bits Lsb ) will contain the messageIDs
   b. The bit 15-22 will represent the destination module,
      and the 23-30 will represent the source module which is
      initiating the message.
   c. Bit 31 will represent whether the message is from host
      or from FW. If bit is 0, it indicates the message is
      from host and if it is 1 it indicates the message is
      from FW.
2. Second field will be constructed using below bit positions:
   a. First 16 bits (From LSB )will be used for counter.
   b. Next 8 bits would be the vdev id.
   c. Remaining 8 bits are reserved for future use.

Here counter is static unsigned 16 bit value which will be
used to keep track of number of logs given to QXDM and out of
these logs how many logs have been missed.
