Add support for native PHP8 QueryParam, FileParam and RequestParam attributes

[W0rma]

Closes #2301

[GuilhemN]

Shouldn't we add bc layers for these classes, like symfony does?

[W0rma]

@GuilhemN I guess you refer to the BC layer for the Route annotation.

I'm not sure how such BC layer should look like here.
Before my changes the constructor of the annotations were just empty.

Since all newly added parameters have default values it is still possible to call new QueryParam() and the behavior of this call should not change.

How about making the annotations reader for the FOS\RestBundle\Request\ParamReader class optional? Right now, the class has a hard dependency on doctrine/annotations and all the Symfony classes made the Reader argument optional when attributes support was added.

Good idea. Thank you for the hint! See a0377b2

Amazing feature, this will help us, to use PHP Attributes instead of annotations (we need to import the Class, but looks like unused import).
Thanks for your contribution.

@W0rma do you have anything to add to this PR? I personally think that is fine and I would like to proceed with the merge, what do you think?

[W0rma]

@goetas I tested my branch in a real life project and it worked fine. Therefore, I think it can be merged.

I'm looking forward to the next release with symfony6 and full attribute support :)
