On hybrid CPU like Intel Arrow Lake, JFR reports incorrect number of cores in `jdk.CPUInformation`.

```
$ jfr print --events jdk.CPUInformation test.jfr
jdk.CPUInformation {
  startTime = 10:49:27.692 (2025-09-04)
  cpu = "Intel (null) (HT) SSE SSE2 SSE3 SSSE3 SSE4.1 SSE4.2 Core Intel64"

```

Flight record in above was created on Intel Core Ultra 5 225U. According to datasheet [1], it has 12 cores, 14 threads. Thus JFR should report 12 in `cores`.

We tackled similar issue on JDK-8365633, then we concluded it is difficult to calculate number of physical cores. Thus we might not set correct value at here, but we should avoid to set incorrect value at least.
