  [BOLT][BTI] Add MCPlusBuilder::updateBTIVariant (#167308)

Checks if an instruction is BTI, and updates the immediate value to the
newly requested variant.  
  
This can be used in situations when the compiler already inserted a BTI
landing pad to a location, but BOLT needs to update it to a different
variant.
Example: br x0 to a location with a BTI c.
