Remove extraneous backdrop-blurs across partials

[ragibson]

This should mostly fix #994 and partially address #907.

• Removes most of the extraneous usage of backdrop-blur with no apparent visual impact (I only kept it on menu-wrapper, menu-blur, nested-menu, background-blur, and search-wrapper)
• Improves number of draw calls in Firefox with header = "fixed" and layoutBackgroundBlur = false by ~200 times, drastically improving scrolling performance
• Improves number of draw calls in Firefox with header = "basic" and layoutBackgroundBlur = true by ~50%

In my earlier testing, I had simply disabled .backdrop-blur, .backdrop-blur-sm, and .backdrop-blur-2xl on every element except for the search widget, but this is a more proper solution. The inclusion of the backdrop-filter on every article link was incredibly intensive and seemingly included as an oversight as it doesn't appear to have any visual effect. That said, please review and check if any of them were actually intended.

Probably more could be done with a better CSS implementation since I did find a lot of documentation saying to avoid these blur filters entirely as they are extremely intensive and often do not perform well on mobile.

The draw call statistics above are from a local build of your website, https://github.com/nunocoracao/n9o.xyz.

Thanks for this @ragibson will need time to review. I will probably merge the PR and make some extra changes. Did you test other setups - aka a config of the theme that doesn't use background-blur?
Those background blurs on the partials were meant for people not using the background blur on the page itself. Might need to revisit this.

Yes, my site has the background blurs disabled and it didn't seem to have any real visual impact (though they definitely have a performance impact). Just wanted to check on the purpose of them on some of the elements that don't *seem* to be visually affected by blur at all. It was included on quite a few.

Give me some time to test this.
