clang-format: use git grep to generate the ForEachMacros list

ojeda · gitster · commit fc7e03aace37 · 2019-06-04T14:50:40.000-07:00
The ForEachMacros list can reasonably be generated grepping
the C source code for macros with 'for_each' in their name.

Taken almost verbatim from the .clang-format file in the Linux kernel.
