taskcluster: Use the mach logger instead of tbpl for stdout logging

It seems that some runs of webkitgtk_minibrowser are still timing out on taskcluster

It will be very useful to me to be able to see the timestamp of the lines printed on taskcluster so that I can see if the issue is caused because the last test ran has hanged or if is another issue.

This PR switches the log handler uses for printing results in stdout for taskcluster from tbpl to match.

The reasons for this:

• With the mach logger a timestamp of when a test starts or ends is printed, which is very useful to detect tests hanging·

• On top of that the mach logger provides a more useful summary at the end of the suite run because it gives information about how many tests (and not only subtests) failed, also it summarizes the cause of the unexpected results (like error or timeout).

• Also, the logs produces by the mach logger are more compact, around half the size in megabytes is needed for storing a log with match (instead of tbpl)

• The environment variable TERM=dumb is passed to disable colors to be printed on the terminal

Automatic update from web-platform-tests
taskcluster: Use the mach logger instead of tbpl for stdout logging. (#19814)

• With the mach logger a timestamp of when a test starts or ends
  is printed, which is very useful to detect tests taking too much
  time to complete or hanging.

• On top of that the mach logger provides a more useful summary at
  the end of the suite run because it gives information about how
  many tests (and not only subtests) failed, also it summarizes the
  cause of the unexpected results (like error or timeout).

• Also, the logs produces by the mach logger are more compact, around
  half the size in megabytes is needed for storing a log with match
  (instead of tbpl)

• The environment variable TERM=dumb is passed to disable colors to
  be printed on the terminal
