CTest: Optionally use a secondary test timeout after matching output

Allow a test N seconds to complete after we detect a matching line in
its output.  Activate this behavior with a new TIMEOUT_AFTER_MATCH test
property.

TIMEOUT_AFTER_MATCH
-------------------
Change a test's timeout duration after a matching line is encountered
in its output.
Usage
^^^^^
.. code-block:: cmake
add_test(mytest ...)
set_property(TEST mytest PROPERTY TIMEOUT_AFTER_MATCH "${seconds}" "${regex}")
Description
^^^^^^^^^^^
Allow a test ``seconds`` to complete after ``regex`` is encountered in
its output.
When the test outputs a line that matches ``regex`` its start time is
reset to the current time and its timeout duration is changed to
``seconds``. Prior to this, the timeout duration is determined by the
:prop_test:`TIMEOUT` property or the :variable:`CTEST_TEST_TIMEOUT`
variable if either of these are set.
:prop_test:`TIMEOUT_AFTER_MATCH` is useful for avoiding spurious
timeouts when your test must wait for some system resource to become
available before it can execute. Set :prop_test:`TIMEOUT` to a longer
duration that accounts for resource acquisition and use
:prop_test:`TIMEOUT_AFTER_MATCH` to control how long the actual test
is allowed to run.
If the required resource can be controlled by CTest you should use
:prop_test:`RESOURCE_LOCK` instead of :prop_test:`TIMEOUT_AFTER_MATCH`.
This property should be used when only the test itself can determine
when its required resources are available.
