removed references of BEFORE/AFTER_COMMIT_VIEW

[evindj]

This PR addresses issue #3418 after this PR recently did the same for tables.
Given that the current implementation of commitTransaction works only for table (from my reading, please correct if I am wrong), I concluded only removing events would be enough especially since *ReplaceView is already supported.

Tests:

Ran integration tests.

@snazy please have a look. I closed #3441 in favor of this after mixing up the rebase.

The change LGTM!

In the future, please just rebase the existing PR (#3441) instead of opening a new one.

I'm catching up here and saw this related conversation:

https://github.com/apache/polaris/pull/3195/changes#r2593440033

I'm not sure I agree with keeping these constants. Granted the ordinals will change if we remove them. But the feature is in beta status right now. It feels odd to see deprecated/unused constants in an API that is not even "official" yet.

@adnanhemani @dimas-b what do you think?

[dimas-b]

I do not see any particular issue with changing ordinals. AFAIK, Polaris does not use java serialization for this enum and Jackson deals with names.

[evindj]

If we are to remove the constants, will be ok doing in a follow up PR?cc @adutra I can take ownership of that issue as well.

[snazy]

I think doing it in a separate PR makes sense, so the two other similar enum values can be removed as well.
