[jdk15u-dev] RFR: 8247872: Upgrade HarfBuzz to the latest 2.7.2

Mon Nov 29 10:47:41 UTC 2021

It's proposed to upgrade HarfBuzz to 2.7.2 in 15u.

The new version uses c++11 features, so the patch added a new flag (-std=c++11) when building the libfontmanager library.

Tested with tier1 on platforms: Windows x86/x86_64 (VS 2017), Linux x86/x86_64 (gcc 8.3.0), Mac OS X x86_64 (XCode/Clang 11.0)
