Revert of remove guarded code - there are no more callers

Revert of remove guarded code - there are no more callers (https://codereview.chromium.org/343783002/)

Reason for revert:
webkit still uses getTotalClip -- need to find where they define the guard.

../../skia/ext/skia_utils_mac.mm:400:42: error: no member named 'getTotalClip' in 'SkCanvas'
      const SkRegion& clipRgn = canvas_->getTotalClip();
                                ~~~~~~~  ^

Chromium defines the guard in skia/:

skia/BUILD.gn:    "SK_SUPPORT_LEGACY_GETTOTALCLIP",
skia/skia_common.gypi:      'SK_SUPPORT_LEGACY_GETTOTALCLIP',

Did we just find another client for getCurrentClip()? :)
