Add support for easily collecting JitFuncInfoLogFile for the tests

Simply uncomment one of the three methods for doing the collection in
the ryujit_x86_testenv.cmd file.

+@REM the same directory as the test. Note that each tests lives in
+@REM its own directory, and the current directory is set to the unique
+@REM test directory before this script is invoked.

+@REM them in a separate directory tree rooted at %__FuncInfoRootDir%.
+@REM If that is set globally already, then use it. Otherwise, use a
+@REM default set here. The directory tree will mirror the test binary tree.
