S3 never lists an empty result for another region: a valid region
other than the endpoint's own gets 400 InvalidArgument, "Requests with
bucket-region specified must be made to the corresponding regional
endpoint", with no ArgumentValue. The gateway is a single regional
endpoint, so it now does the same instead of clearing the listing.
Match the region case-insensitively like S3, and check an empty
bucket-region= too by looking for the query argument itself, since an
empty value is not a valid AWS region either.
ListBuckets ignored bucket-region: a value that is not a region was
accepted, and a region other than the gateway one still listed every
bucket. S3 rejects an invalid value with 400 InvalidArgument, "Argument
value abc is not a valid AWS Region", and lists only the buckets of the
requested region.
Check bucket-region against the AWS region code format, always
accepting the gateway region whatever its name, and return an empty
list for any other region, since every bucket lives in the gateway
region. Enable the REST tests that cover both cases.

A bucket GET with both the uploads and uploadId query parameters was
routed to ListMultipartUploads and answered with the upload listing.
S3 rejects the combination with 400 InvalidArgument, "Conflicting query
string parameters: uploadId, uploads".
Add an error route for the combination ahead of ListMultipartUploads,
the way the object level '?uploads' request is rejected, and enable
the REST test that covers it.
Fixes#2155
A region specific endpoint requires CreateBucket to name that same region
in `LocationConstraint`. The gateway reported a mismatch as
`InvalidLocationConstraint`, which AWS reserves for a constraint that is
not a valid location at all, and accepted a request that omitted the
constraint entirely.
Keep `InvalidLocationConstraint` for the global `us-east-1` endpoint,
which takes no constraint, and return
`IllegalLocationConstraintException` when a region specific endpoint gets
a constraint naming another region, or none.
Fixes#2246
