replace context macro usage with inline function calls

[gauravharsha]

Update all utils::context. call sites to utils::context(). following the replacement of the context preprocessor macro in green-utils with an inline function. Depends on Green-Phys/green-utils#5, Green-Phys/green-opt#8 and Green-Phys/green-sc#12

Pull request overview

This PR updates Green-GPU to match the upstream change in green-utils where utils::context moved from a preprocessor macro to an inline function, requiring call sites to use utils::context().….

Changes:

• Replaced utils::context.… / green::utils::context.… member access with utils::context().… / green::utils::context().… across GPU kernels and tests.
• Updated MPI communicator/rank accesses (global, global_rank, node_rank, internode_comm, etc.) to route through the new context() accessor.
