Add has_size option

[simonbray]

Allows checking file size in tests directly without having to use sim_size and a test file. See #8838

Some questions:

• I guess I should write a test, where should this go?
• galaxy.xsd would also have to be updated in the planemo repo, should I also submit a PR for that?
• how can I edit the docs? The source for https://docs.galaxyproject.org/en/latest/dev/schema.html doesn't seem to be on github.

As far as I can tell there are no unit tests for test assertions. If you want to write these that would be awesome, it should be relatively straightforward. I think it's also OK if you just add the assertion to one of the test tools in test/functional/tools.

• galaxy.xsd would also have to be updated in the planemo repo, should I also submit a PR for that?

We're going (or maybe we already did?) to refactor planemo to get this file from the tool_util package, so no.

• how can I edit the docs? The source for https://docs.galaxyproject.org/en/latest/dev/schema.html doesn't seem to be on github.

It'll be generated from the schema

I've got a WIP patch locally, but first we need to address common-workflow-language/cwltool#1155
