only alert when inserting a suggestion make additional editor, like inserting an import statement, simplify the message that read when selecting an item

Removed reporting the number of times alerted string appeared, which has no use for a blind user, and causes too much verbosity.

Changed verbosity of code completion widget alerts to provide the current completion item without unnecesary snippet/regular hints, or if items have details.

Assigned an empty string to silence too verbose alerts, which try to handle function, much better handled by the screen readers, and therefore they should be removed.

Add strict null checks to suggestMemory.test.ts

Prototype autoFix source code action

Apply auto fix on save actions sequentially and make sure we request fixes of the specific type we are interested in

We likely do not want to enable autofixes until we have proper TS support: https://github.com/Microsoft/TypeScript/issues/29452

Part of #62110

* Adds a new `CodeActionKind`: `source.autoFix`.
* Implements a simple auto fix provider for typescript. This provider can auto fix `implement interface` and `spelling` errors (provided there is only a single valid fix listed)

The provider is likely not something we actually want to check it (especially in its current state), we should ask TS for proper autoFix support
