Requesting merge of https://chromium.googlesource.com/chromium/src/third_party/freetype2/+/fb0d66d04c4dd8d7f9604af1a6001b2737cb5098 (along with a few small security fixes) to M71, which would mean landing this roll of FreeType https://chromium-review.googlesource.com/c/chromium/src/+/1327228 to branch 3578.

These changes are in 72.0.3606.0 and have been observed to fix the issue.

The effect of the issue being fixed here is that certain variable fonts will have random glyphs not draw (as if the glyph data were corrupted). This was discovered on axis-praxis, which is a fairly high profile font design site, so we would like to not ship M71 to stable with this issue.

Approving merge to M71 branch 3578 based on comment #5. Please merge ASAP.
