Junyuan 6852a2e267 [feat] add LMCacheAscendConnector (#6882)
### What this PR does / why we need it?

LMCache-Ascend is LMCache's solution on the Ascend platform and one of
the KVCache pooling solutions for Ascend. We hope to integrate
LMCache-Ascend into the vLLM-Ascend community as one of the official
KVCache pooling solutions for vLLM-Ascend.

We added a new LMCacheAscendConnector in vLLM-Ascend and registered it.

### Does this PR introduce _any_ user-facing change?

Users can specify the kvconnector using `--kv-transfer-config`, allowing
them to freely choose which kvconnector to use, without any user-facing
change.

### How was this patch tested?

Test by specifying `--kv-transfer-config
'{"kv_connector":"LMCacheAscendConnector","kv_role":"kv_both"}'`

- vLLM version: v0.16.0
