feat: oauth revamp + support for multiple grant types in oauth

[amk-dev]

This PR introduces support for the following oauth grant types.

• Authorization Code
• Authorization Code + PKCE
• Client Credentials
• Password
• Implicit

[VVelox]

This actually going to get accepted, I wonder, given the fate of #3266 ?

• All Grant Types require a Pass by field to indicate whether to include OAuth data as part of request headers/URL.

• There's an exception while opting for OAuth 2.0 as the Authorization Type for a GraphQL request.

• The fields for Basic Auth & Bearer Token Authorization types aren't displayed. Applicable to the modal aimed at setting authorization at the collection level.

LGTM 🚀
There's an issue persisting, about a mismatch in schema while saving the state in the modal for setting authorization/headers at the collection level. A fix for the same is landed on the release branch and should be resolved along with the rebase.
