[rocprofiler-register] Fix compilation with system fmt/glog (#1243)

rocprofiler-register provides options to build with system glog and fmt: `-DROCPROFILER_REGISTER_BUILD_GLOG=OFF -DROCPROFILER_REGISTER_BUILD_FMT=OFF`.
However these options don't work, because attempt to call
```cmake
find_package(glog REQUIRED)
...
find_package(fmt REQUIRED)
```
in the **nested** `external/CMakeLists.txt` does not expose glog and fmt to the **parent** `CMakeLists.txt`.
To make projects visible, the easiest way is to add `GLOBAL`:

```cmake
find_package(glog REQUIRED GLOBAL)
...
find_package(fmt REQUIRED GLOBAL)
```

GLOBAL modifier requires CMake >= 3.24, which was not required in
ROCm/rocm-systems, but ROCm/rocm-libraries already requires 3.25,
so this change should be safe.

Closes #1242.
