[cfe] Add implicit null-check on throw

Throwing `null` is not supported in sound null safety. This change
inserts an implicit `as Object` cast that result in a TypeError, rather
than a NullThrownError, in sound mode.

Closes https://github.com/dart-lang/sdk/issues/49198

TEST=Covered by the existing tests
