fix(cpp) exclude keywords from function calls

[Eisenwave]

Related to #4214.

The highlighter for C++ behaves treats keywords followed by parentheses as function calls (with some exceptions), and this is harmful:

// highlighted as a function call, but is grammatically a declaration
static_assert("");

// providing a reason for deletion should not be a function call!
void awoo() = delete("reason");

// highlighted as a function call, but that is slightly forgivable
// because it's called "function-style cast"
int(0);
// ... but then why is a function-style cast with braces not a function call?!
int { 0 };
// ... and why is this other cast not a function call?!
(int) x;

In general, it is wrong to highlight keywords followed by parentheses as function calls. This is always wrong, not just in specific cases like for() or if().

Changes

Exclude all keywords followed by parentheses from being classified as function.dispatch = built_in.
