Finish release (opt) builds on Windows, including the parallel

build\*.scons structure (mirroring build\*.vsprops files):
* Use env.ApplySConscript() instead of env.SConscript with a
  hand-crafted dictionary defining 'env'.
* Move various CPPPATH, CCFLAGS, CPPDEFINES, LIBS and LIBPATH
  definitions from build/SConscript.main and target-specific 
  *.scons files into the build\*.scons files that mirror the
  existing build\*.vsprops hierarchy.
* Use the new build\{debug,release}.scons files to update the
  windows_dbg and windows_opt construction environments.
* Mirror current support for CHROME_BUILD_TYPE and CHROMIUM_BUILD
  external environment variables.
* Remove hard-coded /TP options.
* Massage $CXXFLAGS to remove $CCFLAGS, avoiding duplication of options
  on command lines.  Handle the ripple effect in $PCHCOM by adding
  $CCFLAGS back to that command line.
* Delete hammer's default settings of {CC,LINK}FLAGS_{DEBUG,OPTIMIZED}
  so they don't pollute our construction environments.
* Update chrome config to link against v8 for opt, v8_g for dbg.
* Get rid of fragile by-hand order of using_net.scons before other
  using_*.scons files.  We're now using --start-group and --end-group
  on Linux to deal with dependency cycles in libraries.
