Generate ETW events in Chrome Frame under the control of the same env var as Chrome.
Generate ETW events in Chrome Frame under the control of the same env var as Chrome.

CHROME_ETW_LOGGING env var now controls whether or not npchrome_frame.dll generates ETW events.  This matches the behavior in chrome.exe.  I also tweaked the log settings so that the same info is included in npchrome_frame.dll log messages as those in chrome.exe.

TEST=none
