Add `MessageClass`, rework `Severity` and add `DiagnosticReason`.wip/adinapoli-message-class-new-design
Other than that:
* Fix T16167,json,json2,T7478,T10637 tests to reflect the introduction of
the `MessageClass` type
* Remove `makeIntoWarning`
* Remove `warningsToMessages`
* Refactor GHC.Tc.Errors
1. Refactors GHC.Tc.Errors so that we use `DiagnosticReason` for "choices"
(defer types errors, holes, etc);
2. We get rid of `reportWarning` and `reportError` in favour of a general
`reportDiagnostic`.
* Introduce `DiagnosticReason`, `Severity` is an enum: This big commit makes
`Severity` a simple enumeration, and introduces the concept of `DiagnosticReason`,
which classifies the /reason/ why we are emitting a particular diagnostic.
It also adds a monomorphic `DiagnosticMessage` type which is used for
generic messages.
* The `Severity` is computed (for now) from the reason, statically.
Later improvement will add a `diagReasonSeverity` function to compute
the `Severity` taking `DynFlags` into account.
* Rename `logWarnings` into `logDiagnostics`
* Add note and expand description of the `mkHoleError` function
