Implement nextUrl for OpenID Authentication

[cwperks]

Description

Adds support for nextUrl in OpenID Authentication. This change also supports nextUrl for multi authentication.

If a user's session times out, they will resume where they previously left off instead of being directed back to the home page.

This change is modeled off of similar work done for SAML:

Testing

Tested using a keycloak IdP in local development. Opening this PR up as a draft as functional tests are written for this change to verify the new behavior.

I'm pushing the function test repo to update to Cypress12 which has official support for cross-origin testing: opensearch-project/opensearch-dashboards-functional-test#801

@cwperks Are you still working on this? Do you need extra hands to get this through?

[DarshitChanpura]

It will be picked back up once #1579 is merged

[cwperks]

@RyanL1997 @derek-ho @DarshitChanpura This is ready for review.

[RyanL1997]

Hi @cwperks, thanks for putting this up, and I just left some comments.

[RyanL1997]

Btw I think we need to update the branch with the latest changes

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.x 2.x
# Navigate to the new working tree
cd .worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-1563-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 6374198119fcb2b33343460a3d2fdfcb44794f30
# Push it to GitHub
git push --set-upstream origin backport/backport-1563-to-2.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-1563-to-2.x.

I'll open up a manual backport for this.
