Why

Don't require adding 'cuda' to UCX_TLS (when setting UCX_TLS explicitly) in order to detect GPU memory.

How

  • Introduce UCX_MEM_TLS config param that configures memory detection transports
  • Keep MD and resource in the context if it is used for memory detection (even if not used for transports), but don't use it for communication.

Separate memory detection transports config to a new variable -
UCX_MEM_TLS. This way, setting UCX_TLS will not affect the ability to
detect GPU memory.
