Fix bugs checking va_start in lambdas and erroneous contexts Summary: First, getCurFunction looks through blocks and lambdas, which is wrong. Inside a lambda, va_start should refer to the lambda call operator prototype. This fixes PR32737. Second, we shouldn't use any of the getCur* methods, because they look through contexts that we don't want to look through (EnumDecl, CapturedStmtDecl). We can use CurContext directly as the calling context. Finally, this code assumed that CallExprs would never appear outside of code contexts (block, function, obj-c method), which is wrong. Struct member initializers are an easy way to create and parse exprs in a non-code context.
