wxiaoguang 6cee3bfa96 Refactor markup render to fix various path problems (#34114)
* Fix #33972
    * Use consistent path resolving for links and medias.
* No need to make the markup renders to resolve the paths, instead, the
paths are all correctly resolved in the "post process" step.
* Fix #33274
* Since 1.23, all paths starting with "/" are relative to current render
context (for example: the current repo branch)
* Introduce `/:root/path-relative-to-root`, then the path will be
rendered as relative to "ROOT_URL"
