This is a direct follow-up to antrea-io#6465. We implement the same changes to
enable faster local code generation, but this time for the multicluster/
folder and its generation script.

We also ensure that mocks are regenerated by the script by default, to
ensure that they don't fall out of sync.

For [CVE-2024-24790](https://nvd.nist.gov/vuln/detail/CVE-2024-24790)

The vulnerability is currently flagged by scanners with CRTICIAL
severity. After review, I do not think this vulnerability can really be
exploited in the context of the antrea-agent.

…antrea-io#6472)

We wait (for a maximum of 5s) for the datapath_id of the br-int OVS
bridge to be reported in OVSDB, after creating the bridge and before
checking supported datapath features. This prevents errors when querying
the supported features before the ofproto-dpif provider has been
initialized.

Fixes antrea-io#6471

The version of the mockgen binary included in the codegen image should
match the version of the go.uber.org/mock module that we use.

There was a small change in formatting of generated files (extra empty
line), which is why all generated mock files are updated as part of this
PR...

…rea-io#6447)

This commit introduces an interface defining methods for managing a BGP
(Border Gateway Protocol) process. Currently, only the goBGP implementation
is available, but more implementations might be added in the future.

The controller for the BGPPolicy CRD will be added in a subsequent PR.
It will configure the BGP process appropriately using this interface.

PRs antrea-io#6447 and antrea-io#6477 got merged around the same time, and the mock file
for the BGP interface was not generated using the latest mockgen
version.
