Add SPDLOG_TO_VERSION to compare spdlog version (#2853)

Browse Source 
You can use SPDLOG_VERSION to select the latest spdlog features
where available while falling back to older implementations otherwise.
Using SPDLOG_TO_VERSION() for the value to compare with is recommended.
for Example:
```c++
 void sink_it_(const details::log_msg &msg) override
 {
 #if SPDLOG_VERSION < SPDLOG_TO_VERSION(1,4,0)
     fmt::memory_buffer formatted;
 #else
     memory_buf_t formatted;
 #endif
     sinks::base_sink<Mutex>::formatter_->format(msg, formatted);
     // bala bala...
 }
```
