perf: use array of html struct instead of plain HTML Element

[ghiscoding]

• the previous migration to plain/pure HTML Element was great for CSP but keeping a large array of HTMLElement can consume a lot of memory and is not the fastest especially when dealing with large dataset (thousand of items), what we can do instead of keep a minimal html struct (html tag name and the props/attrs that we are interested only), so whenever we need to recreate the list of element it is much quicker to create basic struct than it is to create thousand of HTMLElement and it consumes a lot less memory.
• perf seems to double when using html struct instead of plain HTMLElement
• the perf comparison was mostly done in the Large Dataset example which is where this PR will have the biggest impact
