refactor: rewrite ReportGenerateRow in React

[yudukikun5120]

@mkobayashime I'd to hear your impression of the reimplementation using React (e.g. whether the not over complex manipulations like ReportGenerateRow should be implemented with plain DOM API or React).

I think a disadvantage of using React over the pure DOM APIs is it makes the final bundle size bigger and loading time longer (in this case contentScript/reportTemplate.js will include the whole React runtime) in general, but we can virtually ignore it when it comes to Chrome extensions where all assets are downloaded/saved in the local disk beforehand, so we can use React without hesitation (this also is a reason why I chose React instead of Preact). Please note that this doesn't mean all existing DOM modification codes have to be rewritten with React: we can still use pure DOM APIs for simple manipulation and rewrite them when it become too complex to be done with pure DOM APis.
