Enable building "extra tests" with a newer C++ standard

Browse Source 
"extra tests" are defined in test/CMakeLists.txt for FLTK devs to allow
quickly building test programs with minimal edits. The new feature
can be used to set a higher C++ standard for these test programs.
See instructions in test/CMakeLists.txt.

Note: this is only intended to be used for quick tests and *must* not
  be committed and pushed to the main repository for obvious reasons.

# Define additional example programs for testing, for instance:
# set(extra_tests issue-276 str-1895)
# Use the source file test/'name'.cxx for each additional program.
# These test programs will be built with image and GL libraries.
# Leave the variable 'extra_tests' empty to disable extra test programs.
# These test programs will be built with image and GL libraries. Leave
# 'extra_tests' empty (default) to disable extra test programs.
# Instead of adding the tests to the variable in the 'set' command you
# can also add it with `list(APPEND extra_tests test1 test2)` etc..
# See commented example at the end of this paragraph.
set(extra_tests)
# Uncomment the following statement to set the C++ standard for your
# extra test(s), or add more such lines, using "TEST_cxx_standard" as
# variable names (replace 'TEST' with your program name), and set the
# variable to one of { 14, 17, 20, 23 } for C++14, C++17, ... resp..
# The default is not to change the C++ standard, i.e. compile with
# C++11 or whatever the user chose to build the FLTK library.
# set(TEST_cxx_standard 20)
# Example code (do not uncomment these examples):
#------------------------------------------------
# set(extra_tests test1 test2 test3)
# set(test2_cxx_standard 17)
# set(test3_cxx_standard 20)
#------------------------------------------------
# This would build test1(.cxx) with default settings, test2 with C++17,
# and test3 with C++20.
