Replace moment with dayjs

[cktang88]

What did you implement

Closes #7022

Build size should be much smaller now, since dayjs is around 60kb less than moment gzipped.

dayjs: https://bundlephobia.com/result?p=dayjs@1.8.17
moment: https://bundlephobia.com/result?p=moment@2.24.0

@medikoo can you take a look at this?

@cktang88 Thank you! Looks good, still I'd rename vars to dayjs, as otherwise it may confuse devs they rely on moment specifically when reading the code (and require is on top of the file it can be missed).
