vim-patch:2a33b49: runtime(make): syntax highlighting update for makeDefine (#36158)

Previously contents in makeDefine are nearly highlighted as Define, so
comments and targets shares the same color as Define, making it hard to
distinguish if someone write large block of targets-recipes as defined
function.

Such scenario is common in building data analysis pipeline. Recipes are
reused and targets may have multiple variables, and a single % implicit
rule is not enough.

closes: vim/vim#18403
