Dynamic memory allows users to allocate fast shared memory when a kernel
is launched. We used to support a single size for all kernels via the
`LIBOMPTARGET_SHARED_MEMORY_SIZE` environment variable but now we can
control it per kernel invocation and use computed values.

Note: Only the nextgen plugins will allocate memory based on the clause.
