Support ES Decorators

[hasezoey]

Describe what you need | want

Typescript 5.0 has added support for ES Decorators and Typescript 5.2 has added support for ES Decorator metadata

Do you have already an idea for the implementation?

yes, see branch feature/try-new-decorators

full implementation currently blocked by:

• Decorator return type has to be any or would have to provide 2 decorators, one each returning PropertyDecorator/ClassDecorator(old decorator type) and ESClassFieldDecorator/ESClassDecorator(new decorator type, manual); otherwise typescript errors with Unable to resolve signature of property decorator when called as an expression. for property decorators, see @prop as a example
• Property decorators do not have access to the class or the class name, making logging harder Suggestion: Provide additional context about the class to member decorators tc39/proposal-decorators#466, see this line
• typescript does not output decorator type metadata for the new ES Decorators
• a good way to test without having to completely copy the whole test-suite
• default classes which use decorators cannot be provided anymore because decorator settings may be different than the typegoose project and then be incompatible
• typescript 5.2 requirement (and waiting for this version to be released)
• reflect-metadata (or any other) will not be installed / run by default anymore, fixes Allow alternatives to reflect-metadata for shimming reflect metadata API #761

PS: the branch feature/try-new-decorators is just a testing implementation, it is not meant to actually be merged in its current state (its using WIP commits and the tests are not fixed)

as a note, typescript 5.2 has now been released (not just beta)
