Update BSOD guide - Mention how to read MCEs

[Mr-KayZ]

• In the WHEA (0x124) section, mention to remove the first 8 bits in the MCI status codes as they are 32 bit numbers, the whole args are in 64 bits. As Jim stated "Yeet the first 8 digits from both arg 3 and 4":
  

• For MCEs, write how Windows was capable of analyzing that from here: https://discord.com/channels/749314018837135390/1158381689412788264/1268997683964674169

• Also update the gathering dumps part where if the pagefile is too small, dumps will fail to be created. This can also be seen when you ask them to run ?eventviewerlogs and see volmgr failing to create dumps. That means it is pagefile.
