Add missing vSphere E2E tests

[sp1999]

Description of changes:

This PR does the following in the vSphere E2E tests:

• For packages tests, it adds the missing E2E tests for kubernetes v1.29 as they weren't added when we first started supporting it in Add 1.29 VSphere E2E tests #7562.
• It also updates all the kubernetes v1.27 and v1.29 packages tests to regional curated packages tests as a follow-up to Curated packages tests using regional packages for vSphere #8569.
• For all other tests, it adds the missing kubernetes v1.26 and v1.27 tests to cover all scenarios. For tests which have only test for an older kubernetes version, it updates that test to the latest kubernetes v1.30.

Overall, this PR adds 42 new vSphere tests and we had ~340 tests so far. So this will bring the total E2E tests count to ~380 which is above 360. This will set the testPerInstance value to 2 causing two tests to run sequentially on each instance. In order to bring it back to 1, this PR also increases the max EC2 count from 180 to 200.
