[Patch] iosxwstr WideCompareStr failure
## Summary
`WideCompareStr` with `iosxwstr` returns unexpected results - tests fail
## System Information
- **Operating system:** macOS Ventura 13.6.1
- **Processor architecture:** x86-64
- **Compiler version:** trunk
## Steps to reproduce
On macOS, run fpc tests. [tunistr7.pp](tests/test/tunistr7.pp) and [twide7.pp](tests/test/twide7.pp) will fail with exit code 2.
## What is the current bug behavior?
`WideCompareStr("afcde", "aécde")` returns -1. The tests expect it to be positive, like on other platforms (verified on linux x86_64).
## What is the expected (correct) behavior?
`WideCompareStr("afcde", "aécde")` returns 1.
## Relevant logs and/or screenshots
The following Objective C output shows that a normal `NSString :compare` actually equals to calling `CFCompareString` with `kCFCompareNonliteral` and that the explicit option `NSLiteralSearch` equals to calling `CFCompareString` with 0:
```objective_c
//
// main.m
// TestCFStringCompare
//
#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
@autoreleasepool {
NSString* w1 = @"afcde";
NSString* w2 = @"aécde";
NSComparisonResult cr = [w1 compare:w2];
NSLog(@"NSString compare: result is %ld", (long)cr);
cr = [w1 compare:w2 options:NSLiteralSearch];
NSLog(@"NSString compare: with NSLiteralSearch result is %ld", (long)cr);
CFStringRef cfw1 = (__bridge CFStringRef)w1;
CFStringRef cfw2 = (__bridge CFStringRef)w2;
NSLog(@"CFStringCompare result is %ld", (long)CFStringCompare(cfw1, cfw2, 0l));
NSLog(@"CFStringCompare Nonliteral result is %ld", (long)CFStringCompare(cfw1, cfw2, kCFCompareNonliteral));
}
return 0;
}
```
outputs
```

Program ended with exit code: 0
```
## Possible fixes
CFCompareString should be called with kCFCompareNonliteral.
