feat: add a field to disable the auto mutation of endpoints to S3 com…

What's changed and what's your intention?

PLEASE DO NOT LEAVE THIS EMPTY !!!

Please explain IN DETAIL what the changes are in this PR and why they are needed:

At the time of writing, RisingWave will automatically mutate the endpoint to a virtual hosted style. It's a bit confusing and will cause problems when a user is using a S3 compatible service that doesn't support accessing with virtual hosted style endpoints.

The PR adds a field disableAutomaticVirtualHostStyle under the spec.stateStore.s3 to let the user decide when to disable the automatic change of style. Recommended ways to explicitly set the styles are as follows.

# path style
spec:
  stateStore:
    s3:
      endpoint: https://xxxx
      disableAutomaticVirtualHostStyle: true

# virtual hosted style, replace ${BUCKET} manually or leave it there. 
# In the latter one, it will be automatically replaced by the operator.
spec:
  stateStore:
    s3:
      endpoint: https://${BUCKET}.xxxx
      disableAutomaticVirtualHostStyle: true

The field takes effect by setting environment variable RW_IS_FORCE_PATH_STYLE=true in containers.
