(C++) Integer literals with quote delimiters in #defines break highlighting

**Describe the issue**
[Integer literals](https://en.cppreference.com/w/cpp/language/integer_literal) in C++ may be written as 1'000'000'000 instead of 1000000000 for greater readability. When this is used inside a `#define`, if breaks highlighting which treats the rest of the code as being inside a string.

**Which language seems to have the issue?**
cpp

**Are you using `highlight` or `highlightAuto`?**
highlight

**Sample Code to Reproduce**

```
#include
#define INF 1'000'000'000

int main() {
int a = INF;
return 0;
}
```

**Expected behavior**
The token 1'000'000'000 should be highlighted as a number, and the following code should also be highlighted normally, instead of as if it is inside a string:


**Additional context**

The snippet below seems to be highlighted fine, so the issue is likely the interplay between quote-separated literals and defines.

```
#include

int f(int x) { return f(2'000); }

int main() {
int a = 1'000'000'000;
int b = f(1'000);
return 0;
}
```

Inspect the C++ grammar used by highlight, not highlightAuto, and reproduce the problem with the provided #define sample. Done means 1'000'000'000 is highlighted as a number, following code receives normal highlighting, and the non-define examples remain correct.
