feat: `Deno.{stdin,stdout,stderr}.isTerminal()`, deprecate `Deno.isatty()` (#22011)

This change:
1. Implements `Deno.stdin.isTerminal()`, `Deno.stdout.isTerminal()` and
`Deno.stderr.isTerminal()`.
2. Deprecates `Deno.isatty()` for removal in Deno v2, in favour of the
above instance methods.
3. Replaces use of `Deno.isatty()` with the above instance methods.
