feat: option to force dynamic jsx precompile props

[marvinhagemeister]

There are scenarios where framework plugins want to be able to intercept creation of properties. Some Fresh plugins like the current unocss and twind plugin want to intercept all class/className props to render CSS. All other properties not in the list should be treated as usual.

const a = <div class="foo" />

// Before: Not interceptible
const tpl = [
  '<div class="foo"></div>'
]
const a = jsxTemplate(tpl)

// After: interceptible if prop is excluded
const tpl = [
  "<div ",
  "></div>"
]
const a = jsxTemplate(tpl, jsxAttr("class", "foo"))
