- Limits a call to memset in the kernel to the size of the current
memory offset instead of the total size of memory.
- Adds `extism_plugin_reset` to the C API and `extism::Plugin::reset` to
Rust

Add an example of dynamically linking plugins and a benchmark that does
an apples-to-apples comparison of `reflect` using host functions vs.
`reflect` using a linked wasm module. (To my surprise, the host
functions are a _little bit faster_!)
Further flesh out our runtime benchmarks: add benchmarks for sending
bytes one-way into Wasm linear memory, as well as testing copy-in then
copy-out. This compliments our `reflect` benchmark; we can get a sense
of how expensive the sub-operations are via `echo` and `consume`.
(Notably, we're missing a `produce` or `emit` that purely generates
output and sends it to the host!)
The source of these plugins is available in `extism/plugins` as
`echo.wat` and `consume.wat` [1].

This parameterizes the `reflect` test and calls the `g.throughput` on
each data set to get an idea of our roundtrip throughput. (The changes
follow the "Throughput Measurements" [1] part of the Criterion guide
pretty much to the letter.)
Example output:
```
reflect/reflect 1 time: [208.57 µs 209.05 µs 209.57 µs]
thrpt: [298.23 MiB/s 298.97 MiB/s 299.66 MiB/s]
```

- Removes `Plugin::new_with_manifest` and updates `Plugin::new` to take
wasm bytes or `Manifest` using the new `WasmInput` trait
- Removes `PluginBuilder::new_with_module` in favor of a
`PluginBuilder::new` with a `WasmInput` argument
See #504
Removes CI for the in-repo SDKs, we can remove the actual code closer to
the 1.0 release.

Fixes#545
- Adds a type parameter to `UserData` type to avoid dynamic typing
issues
- Adds KV example from README to `examples/readme.rs` to make sure it
stays in-sync
- Implement `Default` for `UserData<T>` when `T` implements `Default`
- Make `UserData` argument non-optional in `Function::new`,
`UserData::default()` can be used instead.
- Adds benchmarking, run with `cargo bench` or `cargo criterion`
- Adds `MemoryRoot::pointer_in_bounds_fast` to do less precise bounds
checking in loads/stores
