* 6.4:
  [Dotenv] Fix self-referencing variable resolution with suffix/prefix
  [Serializer] Fix isAllowedAttribute() when groups contain wildcard '*'
  [DependencyInjection] Fix instanceof autoconfiguration for anonymous classes
  [Cache] fix test

`resolveLoadedVars()` iterated over every name in `SYMFONY_DOTENV_VARS`,
including vars resolved by a previous `load()`/`loadEnv()` call. By then,
the `\x00` markers protecting literal `$` (from single-quoted values) had
already been converted back to `$`, so a value like `This$isokay` was
re-interpreted as a `$isokay` variable reference and truncated to `This`.

Track the names actually populated during `doLoad()` and limit
`resolveLoadedVars()` to that set, leaving previously-resolved values
untouched.

* 6.4:
  [VarExporter] Don't warn for __sleep()-listed uninitialized typed properties
  [Dotenv] Fix variable corruption when loading env more than once
