Remove IBM Feature PR toolchain changes accidentally included in CCE fix branch

Remove test cases (2 MPI Ranks IBM Sphere, IBM Periodic Circle, 2D IBM
STL), parameter limit changes (num_ibs/num_patches max 1000), and code
formatting from the IBM Feature Improvements PR (#1157) that were in the
branch but not in master. These caused CPU test failures (2EE0C3AA,
AFBACA70, 4E0FBE72 tolerance mismatches) on the new CI run.
