- Removes the `ExtismContext` type from runtime and all SDKs - Removed SDK functions: `extism_context_new`, `extism_context_reset`, `extism_context_free` - All SDKs have been updated, but there are still some TODOs below - Removes `extism_plugin_update` - Plugins can no longer be updated - a new plugin should be created instead - Adds `extism_plugin_id` to uniquely identify plugins - Merges the `extism-runtime` and `extism` crates (there is no longer an `extism-runtime` crate) - Makes `extism::Manifest` an alias for `extism_manifest::Manifest` instead of a distinct type - Adds `MemoryHandle` type to SDKs to refer to blocks of Extism memory that can be accessed in host functions - Improves thread-safety of Plugins, adds C++ test to call a single plugin from multiple threads. - Expands wasmtime bounds to include 12.0
