Request for ABT_rwlock_memory #398
Description
Can we get an ABT_rwlock_memory (along with an ABT_RWLOCK_INITIALIZER and ABT_RWLOCK_MEMORY_GET_HANDLE)? The ABTI_rwlock structure (https://github.com/pmodels/argobots/blob/main/src/include/abti.h#L489) contains only fields that can themselves be statically initialized, so it shouldn't be difficult.
