depends on #1363.

This PR implements console.groupCollapsed as discussed in #1355 and #1363.
When groupCollapsed is called, console goes to 'collapsed mode' and stop printing newlines on logging methods. When further group/groupCollapsed methods are called, console keeps the collapsed mode. When groupEnd which corresponds to the first groupCollapsed call is called, console gets out of 'collapsed mode'.

remaining tasks (all done):

  • use groupCollapsed in testing later in deno_std
  • test case of console.error with

Why not use deno.stdout.write ?

Because this class seems using PrintFunc for any output. Do you think we should use deno.stdout/deno.stderr for any output of console's methods?

@ry I tried to replace printFunc calls with stdout/stderr calls, but I realized that stdout.write is async function and not usable as replacement of printFunc (libdeno.print). Probably we need to have sync version of write first. How do you think?

Right - makes sense - I forgot that the writes to stdout/err are non-blocking.
