Merging all Angular tests into a single file

Merging all of the Angular tests into a single file to cut down on dart2js compile times. Using htmlIndividualConfig to cut down on how many tests are run at a time and to fail individual tests.

Each individual test was taking ~28s locally to compile, now the entire combined test is taking about the same.

This is still disabled overall as the dart2js compilation times are still timing out.

lgtm, some minor suggestions below

https://codereview.chromium.org/133843003/diff/40004/third_party/pkg/generate...
File third_party/pkg/generate_angular_tests.sh (right):

https://codereview.chromium.org/133843003/diff/40004/third_party/pkg/generate...
third_party/pkg/generate_angular_tests.sh:28: cat << END_HEADER > "${test_file}"
consider creating a folder with these template pieces. That might help make this
code easier to follow along, as indentation is not changing because of these
multi-line text blocks.

Basically, it would look something like this:

  cat generate_test_templates/header.txt > $test_file
  local index=0
  for ...
     echo "..." >> $test_file
  done
  cat generate_test_templates/start_main.txt >> $test_file
  ...

https://codereview.chromium.org/133843003/diff/40004/third_party/pkg/generate...
third_party/pkg/generate_angular_tests.sh:46: echo "import '${import_file}' as
test_${index};" >> "${test_file}"
you should be able to leave out the "" here (similar in the other places in this
file)

  echo "..." >> $test_file

FYI - for a future change

https://codereview.chromium.org/133843003/diff/170001/third_party/pkg/generat...
File third_party/pkg/generate_angular_tests.sh (right):

https://codereview.chromium.org/133843003/diff/170001/third_party/pkg/generat...
third_party/pkg/generate_angular_tests.sh:28: echo "$(browser_header)" >
"${test_file}"
I think you can simplify this as:

   browser_header > $test_file

https://codereview.chromium.org/133843003/diff/170001/third_party/pkg/generat...
third_party/pkg/generate_angular_tests.sh:37: echo "$(browser_main)" >>
"${test_file}"
same here and below
