Fix clobbering of the upload size validation (#10059)
* Fix clobbering of the upload size validation

When the validation is set here like this, it overrides validation which has already been setup with a simple '*' rule for the size based on PHP.

If you've defined in the sites yml config something like

    SilverStripe\Assets\Upload_Validator:
      default_max_file_size:
        '[image]': '2m'
        '*' : '1m'

then it will not be respected.

If you review SilverStripe\Assets\Upload_Validator and check the getAllowedMaxFileSize method, you'll see the sizing will be populated (if it hasn't been done before).

You can see it fail by;
- Setup a new SilverStripe site.
- Set your PHP to allow max post / max upload size of 10mb.
- Add the above config to your sites yml file and flush.
- In the CMS you'll be able to upload a 5MB file, when you shouldn't.

* Test that FileField will use size validation if defined

Couple of tests which prove a fix so the FileField and others will use the default_max_file_size setting

* Fix variable name in last commit

This is what happens when you refactor in the github window.
Fix the variable names. This will get squashed once merged.

* Updates the pr - white space and non deprecated method for byte conversion

Remove extra white space to appease the CS. Use the non deprecated method for memstring2bytes

* White space fixes for the phpcs

White space fixes for the phpcs

* Ensure that "memstring2bytes" can handle if an empty or value with no number is passed in

* DEP Bump assets constraint to ensure that change is also pulled in
