Bug 1470528 - Implement CONTENT_FRAME_TIME for the non-webrender codepath. r=sotaro, data-review=francois This commit adds the CONTENT_FRAME_TIME metric which tracks the time from the beginning of a paint in the content process until it is presented in the compositor. There is existing logging for frame latency which tracks from the beginning of a refresh tick until the frame is presented. This is undesirable for this probe as javascript and layout can run in this time period. So this probe uses the existing infrastructure for logging frame latency, but uses a start time from BeginTransaction in layer manager. MozReview-Commit-ID: 5z9LS3tsZTY

To have your bug fix / feature added to Mozilla, you should create a patch and
submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at:

    https://developer.mozilla.org/en/docs/Creating_a_patch
    https://developer.mozilla.org/en/docs/Getting_your_patch_in_the_tree

If you have a question about developing Mozilla, and can't find the solution
on https://developer.mozilla.org, you can try asking your question in a
mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups
are accessible on Google Groups, or news.mozilla.org with a NNTP reader.]

You can download nightly development builds from the Mozilla FTP server.
Keep in mind that nightly builds, which are used by Mozilla developers for
testing, may be buggy. Firefox nightlies, for example, can be found at:
