* [fuzz] Remove some differential fuzz targets

The changes in #4515 do everything the `differential_spec` and
`differential_wasmi` fuzz target already do. These fuzz targets are now
redundant and this PR removes them. It also updates the fuzz
documentation slightly.

@@ -36,13 +36,13 @@ At the time of writing, we have the following fuzz targets:
from scratch.
* `differential`: Generate a Wasm module and check that Wasmtime returns
the same results when run with two different configurations.
* `differential_spec`: Generate a Wasm module and check that Wasmtime returns
the same results as the Wasm spec interpreter (see the `wasm-spec-interpreter`
crate).
* `differential_meta`: Generate a Wasm module, evaluate each exported function
with random inputs, and check that Wasmtime returns the same results as a
choice of another engine: the Wasm spec interpreter (see the
`wasm-spec-interpreter` crate), the `wasmi` interpreter, or Wasmtime itself
run with a different configuration.
* `differential_v8`: Generate a Wasm module and check that Wasmtime returns
the same results as V8.
* `differential_wasmi`: Generate a Wasm module and check that Wasmtime returns
the same results as the `wasmi` interpreter.
* `instantiate`: Generate a Wasm module and Wasmtime configuration and attempt
to compile and instantiate with them.
* `instantiate-many`: Generate many Wasm modules and attempt to compile and
