Add some information to the migration guide about two important potentially
breaking changes in 5.2.

Notes:
* original patch by Richard Purdie:
  https://lore.kernel.org/r/20250126111850.2609298-1-richard.purdie@linuxfoundation.org
  This patch is just reformatting/typo fixes.
* The BB_CURRENT_MC should ideally be documented, but that will come at
  a later point with
  https://bugzilla.yoctoproject.org/show_bug.cgi?id=15709.

This is in the migration manual so we need to explicit what the user 
needs to do.

What needs to be done wrt BB_CURRENT_MC change?

For the removal of TARGET_PREFIX/SDK_PREFIX, I assume a simple tree-wide:

sed 's;virtual/\${TARGET_PREFIX}binutils;virtual/cross-bintuils;'

should do the trick?

Also, all of the above didn't have a dash after ${SDK_PREFIX} or 
${TARGET_PREFIX}.

Cheers,
Quentin
