dependencies: switch from Wasmer to Wasmtime (#3349)

* Remove ForeignFunctionEnv wrapper around PluginEnv

This will enable PluginEnv to be the Store context when migrating to
Wasmtime.

* Pass PluginEnv by value to load_plugin_instance

This will allow removing the Clone impl from PluginEnv when migrating to
Wasmtime as required by the missing Clone impl on Wasmtime's WasiCtx.

* Avoid passing a Store around when an Engine is enough

* Pass PluginEnv to the wasi read/write functions

Wasmtime requires storing the read/write end of the pipe outside of the
WasiCtx. Passing PluginEnv to these functions allows storing them in the
PluginEnv.

* Migrate to Wasmtime

* Switch from wasi-common to wasmtime-wasi

* Reduce verbosity of wasmtime_wasi logs

* Increase startup delay

To wait for all plugins to be compiled.

* Disable some wasmtime features

* Update to Wasmtime 21.0.1
