Allow passing arguments to std/datetime/format()

[paul-greenweb]

Is your feature request related to a problem? Please describe.

The problem is, it seems that the current implementation of datetime/format() doesn't allow to return a date in UTC. It is an important feature for logging purposes.

Describe the solution you'd like

I would like to be able to pass an options object to the formatter.format() function

export function format(date: Date, formatString: string, **options**): string {
  const formatter = new DateTimeFormatter(formatString);
  return formatter.format(date, **options**);
}

Code : https://deno.land/std@0.214.0/datetime/format.ts?source=#L27

I see that the options.timeZone is already implemented in formatter.format()

format(date: Date, options: Options = {}): string {
    let string = "";

    const utc = options.timeZone === "UTC";

Code : https://deno.land/std@0.214.0/datetime/_common.ts?source#L259

Describe alternatives you've considered

I didn't find an easy solution
