* Enable limiting wasip3 resource limits
This commit adds a new `Store::concurrent_resource_table` method which enables getting a handle to the underlying `ResourceTable` used by the concurrent implementation of component-model-async. This can in turn be used to set the max capacity on the table and limit the guest usage of the table.
Closes #11552
* Adjust features
* Fix imports

Fix two security advisories. (#12652)
* Fix two security advisories.
This commit contains merged fixes for two security advisories in Wasmtime:
* GHSA-852m-cvvp-9p4w * GHSA-243v-98vx-264h
This introduces new knobs to Wasmtime to limit the scope of resources that WASI implementations will allocate on behalf of guests. Unlike backports to 41.0.x-and-prior these knobs all have default values which are considered reasonable for hosts if they don't further tune them. The following CLI knobs have been added:
* `-Smax-resources` - limits the total component-model resources a guest can allocate in a table * `-Shostcall-fuel` - a broad limit which enforces that at most this amount of data will be copied from the guest to the host in any one API call (e.g. `string` values can't be too big, `list<string>` can't be quadratic, etc). This fuel is reset on each host function call. * `-Smax-random-size` - the maximal size of the return value of the `get-random-bytes` and `get-insecure-random-bytes` WASI functions. * `-Smax-http-fields-size` - a limit on the size of `wasi:http` `fields` values to avoid infinitely buffering data within the host.
The `http` crate has additionally been updated to avoid a panic when adding too many headers to a `fields` object.
