This PR provides better filtering od Content Types and Languages in the content create widget. It depends on new method \eZ\Publish\SPI\Limitation\Target\Version::createFromAnyContentTypeOf. It also introduces new method in \EzSystems\EzPlatformAdminUi\Permission\PermissionCheckerInterface::getContentCreateLimitations to get Limitations specificaly for Content creation.

I see a huge problem here. In order to get list of restricted content types you need to load all content types. This happens in two places: in ContentCreateType and ContentRightSidebarBuilder. Full list of content types is also loaded by ContentTypeChoiceLoader because it's wrapping another choice loader.

It can cause a huge impact on Persistence cache layer. I'm not sure if this is possible to avoid but it looks like you don't need to wrap ContentTypeChoiceLoader just create new one that will load only needed content types.

Name itself suggests that it should be split into smaller methods :)

I agree that the name of this method was missed

@webhdx I think we have an in-memory cache for Content Types. For the user with a broad set of allowed CT it would be not efficient to load CT, and then fetch ContentTypesGroups for them. Also in this PR, in

ContentCreateContentTypeChoiceLoader

we only filter existing list

$contentTypesGroups = $this->contentTypeChoiceLoader->getChoiceList();

and then

foreach ($contentTypesGroups as $group => $contentTypes) {
  $contentTypesGroups[$group] = array_filter($contentTypes, function (ContentType $contentType) {
    return \in_array($contentType->id, $this->restrictedContentTypesIds);
  });
}

also as @alongosz said #987 (comment) we can do optimization as follow-up
