[swift5] fix modelNamePrefix and -suffix for reserved types

[Jonas1893]

Fixes #11185

We need to check for reserved types which must not be prefixed or suffixed. I added the AnyCodable type to languageSpecificPrimitives which is technically not a language type but a type from dependency. If this is not correct I can add a second array to hold potential reserved public types from dependencies. Please provide feedback what is preferred here

Added a new sample to check for prefix and suffix functionalities

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  For Windows users, please run the script in Git BASH.
• In case you are adding a new generator, run the following additional script :

  ./bin/utils/ensure-up-to-date.sh
  

  Commit all changed files.
• File the PR against the correct branch: master (6.3.0) (minor release - breaking changes with fallbacks), 7.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request. -> @jgavris (2017/07) @ehyche (2017/08) @Edubits (2017/09) @jaz-ah (2017/09) @4brunu (2019/11)

@wing328 fixed. swift5 samples currently must not use default package name but must define a custom name instead

Looks good to me 👍
