- Adds `ExtismContext` instead of global `PLUGINS` registry
- Adds `extism_context_new`, `extism_context_free` and
`extism_context_reset`
- Requires updating nearly every SDK function to add context parameter
- Renames some SDK functions to follow better naming conventions
- `extism_plugin_register` -> `extism_plugin_new`
- `extism_output_get` -> `extism_plugin_output_data`
- `extism_output_length` -> `extism_plugin_output_length`
- `extism_call` -> `extism_plugin_call`
- Updates `extism_error` to return the context error when -1 issued for
the plug-in ID
- Adds `extism_plugin_free` to remove an existing plugin
- Updates SDKs to include these functions
- Updates SDK examples and comments

Adds a script to check which runtime API functions are not used in each host SDK. Provides a coverage report with percent of functions called in each SDK.

This PR fixes an issue where large allocations are currently causing
some arithmetic to wrap which caused a panic.
This was discovered by calling `http_get` on `youtube.com` from the http
example in the Rust PDK
This PR updates `extism_output_get` to return an actual pointer to the
output value (`const uint8_t* extism_output_get(PluginIndex plugin)`
instead of `void extism_output_get(PluginIndex plugin, uint8_t *buffer,
uint64_t length)`), this pointer will only be valid until the next call,
but it makes it possible to access the output data without copying.
The input buffer is also not copied and the same issue applies:
the input buffer must not change during `call`.

This gives host the ability to re-use plugin descriptors instead of
loading a new plugin each time. The plugin memory and everything is
reset, so no state is shared with the newly loaded plugin.
