  [Libomptarget] Make the references to 'malloc' and 'free' weak. (#69356)

Summary:
We use `malloc` internally in the DeviceRTL to handle data
globalization. If this is undefined it will map to the Nvidia
implementation of `malloc` for NVPTX and return `nullptr` for AMDGPU.
This is somewhat problematic, because when using this as a shared
library it causes us to always extract the GPU libc implementation,
which uses RPC and thus requires an RPC server. Making this `weak`
allows us to implement this internally without worrying about binding to
the GPU `libc` implementation.
