[rocprof-sys] Use fmt APIs to construct strings instead of JOIN (#2643)

## Motivation

With the introduction of the new logging system base on `spdlog` library, opportunity shows to replace `timemory` dependent JOIN implementation with `fmt` library `format` and `join` APIs, which are shipped as a part of `spdlog` lib

## Technical Details

Use `fmt` provided APIs to properly format and package strings.
