Add RM_TrimStringAllocation(). (#9540)
This commit makes it possible to explicitly trim the allocation of a
RedisModuleString.
Currently, Redis automatically trims strings that have been retained by
a module command when it returns. However, this is not thread safe and
may result with corruption in threaded modules.
Supporting explicit trimming offers a backwards compatible workaround to
this problem.
