[clang-tidy][modernize-use-starts-ends-with] Add support for compare() (#89530)

Using `compare` is the next most common roundabout way to express
`starts_with` before it was added to the standard. In this case, using
`starts_with` is a readability improvement. Extend existing
`modernize-use-starts-ends-with` to cover this case.

```
// The following will now be replaced by starts_with().
string.compare(0, strlen("prefix"), "prefix") == 0;
string.compare(0, 6, "prefix") == 0;
string.compare(0, prefix.length(), prefix) == 0;
string.compare(0, prefix.size(), prefix) == 0;
```
