[Cherry-pick] Port MoE multi-stream fix to v0.11.0-dev (#3753)

Browse Source 
This PR moves the communication operation of shared experts out of extra
stream because I found that this might cause rtMemcpy related errors
when running shared experts multistream with aclgraph.

Furthermore, I utilize a global variable as extra stream object to avoid
allocating streams for each layer in full-graph mode.
