feat(cli/console): inspect with colors regardless of Deno.noColor

[TTtie]

This PR adds the ability for users to inspect items stylized with ANSI colors regardless of the value of Deno.noColor - for example,

// Assumes that Deno.noColor is "true"
// Old behavior
Deno.inspect({ that: "is a object" }, { colors: true }) // { that: "is a object" }

// New behavior
Deno.inspect({ that: "is a object" }, { colors: true }) // { that: \x1b[32m"is a object"\x1b[39m }

Considerations:

• Until Deno.noColor gets initted, should we assume the user accepts colors in their terminal?
  (currently as it is, colors.maybeColor assumes that terminal colors shouldn't be present)

I'm in favour of this change. It matches Node. Only APIs that write to the terminal should take into account NO_COLOR, not programmatic ones. We should consider it for std/fmt/colors.ts.
