fix: rtl language layout

[meysam81]

Description

So far, every RTL language style has been overwritten in every theme to cover for the unsupported behavior of RTL languages in the platform. This fix will address that and it'll reduce the overhead to do the same in the themes.

With this fix, we won't need to change any theme because the default will be to support the RTL languages even in the face of the default theme.

Reproducing

You'll need to run the devstack, change the language to some RTL language (e.g. ar), and see the style correctly formatted in the default theme and any customized theme that hasn't patched the fix.

@meysam81 can you check why CI is failing?

[meysam81]

@natabene

The CI is failing because of some quality checks when running pylint but I didn't touch any python file so there shouldn't be any concern.

As far as I can tell the XSS linter is failing, which is related to templates and HTML. Is it possible for us to rebase this branch onto master and re-run the checks?

[shimulch]

@davidjoy I've rebased & squashed the changes. Seems like there is no failure anymore.
