[TrilinosApplication] Some minor improvements in MPC B&S

[loumalouomega]

📝 Description

In this PR, changes have been made to the TrilinosBlockBuilderAndSolver class in the file trilinos_block_builder_and_solver.h. The main purpose of the commit is to optimize the synchronization of inactive slave degree of freedom (DOF) information between partitions.

1. It begins by initializing a variable num_inactive_slave_dofs_other_partitions to 0.
2. It then iterates over master-slave constraints, updating mInactiveSlaveDofs and num_inactive_slave_dofs_other_partitions accordingly.
3. After this, it calculates the total number of inactive slave DOFs in other partitions using communication via r_data_comm.
4. If there are inactive slave DOFs in other partitions (num_inactive_slave_dofs_other_partitions > 0), it proceeds to synchronize this information between partitions using communication via r_data_comm. The synchronization process involves sending and receiving inactive slave DOF IDs between different ranks.
