feat: improving the performance of running miniruby

[hydai]

Motivation

Previous discussion: #1016

WasmEdge is designed for the general purpose wasm runtime. However, when running miniruby, we found the performance is worse than other runtimes such as wasmtime, even after using the ahead-of-time compilation.

Details

In this ticket, we expect the following working items:

1. Profile the WasmEdge runtime with miniruby workload and generate profiling reports.
2. Figure out the bottleneck of this workload.
3. Modify the wasmedge runtime / wasmedge ahead-of-time compiler to improve the performance.
