feat: add polyfill of URL.canParse for browser compatibility (#70228)

### Why?

Since `URL.canParse` is incompatible with older browsers like Safari 16,
we added `canParseUrl` util at
#70215.
x-ref: https://caniuse.com/?search=URL.canParse

To improve maintenance, we decided to add polyfill for `URL.canParse`.

Closes NDX-302
