Subject: [PATCH] Fix C++20 compile warning on implicit capture of this with
 '=' default capture (#1833)

Happens when compiled with -std=c++2a, the fix just makes the captures explicit to resolve the issue. Just adding this in addition to = doesn't work in C++11.

src/hb-ot-layout-gpos-table.hh:737:18: warning: implicit capture of 'this' with a capture default of '=' is deprecated [-Wdeprecated-this-capture]
              { return (this+_).intersects (glyphs, valueFormat); })
