Add a wasi-http echo-request component in C
This adds a wasi-http version of luw-echo-request.c[0]
This works under the wasmtime v15 CLI serve command.
e.g
$ ~/src/c/wasm/wasmtime-v15.0.0-x86_64-linux/wasmtime serve c/wasi-http/echo-request/component.wasm
Serving HTTP on http://0.0.0.0:8080/
$ curl localhost:8080/hello
*** Welcome to WebAssembly with wasi-http / C ***
[Request Info]
REQUEST_PATH = /hello
METHOD = GET
QUERY =
[Request Headers]
host = localhost:8080
user-agent = curl/8.2.1
