Expose partial parameters explicitly

[JonKaric]

Bug description

Currently, there is no way to expose all parameters passed to a partial without explicitly knowing the parameters you're passing down. It's possible to look at the view but these look to be merged with the current context, polluting the possible parameters with ones that have been passed previously (nested components, for example, but we also came across this issue with the {{ nocache }} tags returning a different context)

We already know the parameters used on just that partial and we're getting them using the special__frontmatter key. However, this is overwritten somewhere down the line but I couldn't find where.

cms/src/Tags/Partial.php

Line 25 in f52ea08

'__frontmatter' => $this->params->all(),

I think it would be good to create another variable, that isn't touched by anything else. Gives us the ability to not worry about scoping, view context etc. We know explicitly what parameters have been passed to that partial.

 '__params' => $this->params->all(), 

How to reproduce

Just a little test between __frontmatter and __params. You'll find the __frontmatter returns empty arrays.

partial.antlers.html

{{ {__frontmatter } | dump }}
{{ {__params } | dump }}
