LOG: [llvm-profdata] Resolve tilde for weighted input filenames (#146206)

When specifying a weighted input file, the shell does not automatically
expand the tilde (`~`) character in the filename because the argument
is passed as a single string in the format `<weight>,<filename>`.

This commit fixes the issue by using `llvm::sys::fs::expand_tilde` to
explicitly resolve the tilde in the filename, ensuring that paths
like `~/path/to/file` are correctly handled.
