Update Gateway API to v1.3.0

[ciarams87]

Proposed changes

Problem: We don't support the latest version of the Gateway API

Solution: Update Gateway API to v1.3.0

Testing: Ran unit-tests and conformance tests locally

Please focus on: I've enabled the Request Mirroring conformance tests, but they are failing for me locally. Pushing them anyway for now, we can decide if we need to fix something on our side, or disable them for now

Closes #3316

looks good to me, but request mirror conformance tests fail, so we might just have to remove them.

@sjberman why didn't we add them as part of your PR, am I missing something?

[sjberman]

@salonichf5 They were apparently bugged in the last release, but maybe there's still an issue. I verified that the functionality worked, but the tests weren't passing.

aah okay, makes sense now. We might just have to track the bug separately and add these then. I can open the issue, didn't find the bug in issues, can you point me towards it?

[sjberman]

@salonichf5 I had assumed kubernetes-sigs/gateway-api#3708 was a fix for the potential issue we were seeing.

Basically the tests couldn't see an expected log message, but I manually checked the logs and it existed. So something seemed wrong with the test.

[ciarams87]

I'll disable them again and create a tracking issue @salonichf5 @sjberman
