[OpenMP] Simplify variable sharing and increase shared memory size

Authored by jdoerfert on Jul 10 2021, 5:32 PM.



In order to avoid malloc/free, up to NUM_SHARED_VARIABLES_IN_SHARED_MEM
(=64) variables are communicated in dedicated shared memory instead. The
simplification does avoid the need for an "init" and requires "deinit"
only if we ever communicate more than NUM_SHARED_VARIABLES_IN_SHARED_MEM
