Add the PE's IMAGE_LOAD_CONFIG_DIRECTORY for chrome.exe

Add the PE's IMAGE_LOAD_CONFIG_DIRECTORY for chrome.exe

This allows us to add global parameters that
control the behavior of the default process heap. In this
case we need to be less agressive about freeing memory.

Bruce, ptal.

The idea here is to land and see what perf looks like, if there is not a
positive outcome it will be reverted.

A couple of comments, but lgtm.

Whether we should ship it is another question, but it is a worthwhile test.
Apparently setting this will take us down less tested paths that may no longer
be well tuned, so close observation will be important.

File chrome/app/chrome_exe_load_config_win.cc (right):

https://codereview.chromium.org/1133313003/diff/20001/chrome/app/chrome_exe_l...
chrome/app/chrome_exe_load_config_win.cc:9: // as well it but this one will be
used if present.
Missing word 'it': "it as well"...

https://codereview.chromium.org/1133313003/diff/20001/chrome/app/chrome_exe_l...
chrome/app/chrome_exe_load_config_win.cc:18: // and inspect the results.
I also wrote a tool (85 lines of PE parsing) that allows slamming the
DeCommitTotalFreeThreshold of a PE file, FWIW. It also dumps the old value.
Should it be checked in somewhere?
