[PM-19029][PM-19203] Addressing UserService tech debt around ITwoFactorIsEnabledQuery (#5754)

* fix : split out the interface from the TwoFactorAuthenticationValidator into separate file.
* fix: replacing IUserService.TwoFactorEnabled with ITwoFactorEnabledQuery
* fix: combined logic for both bulk and single user look ups for TwoFactorIsEnabledQuery.
* fix: return two factor provider enabled on CanGenerate() method.

* tech debt: modfifying MFA providers to call the database less to validate if two factor is enabled. 
* tech debt: removed unused service from AuthenticatorTokenProvider

* doc: added documentation to ITwoFactorProviderUsers
* doc: updated comments for TwoFactorIsEnabled impl

* test: fixing tests for ITwoFactorIsEnabledQuery
* test: updating tests to have correct DI and removing test for automatic email of TOTP.
* test: adding better test coverage
