Disable arity limit in HTTP clients

[kubukoz]

Currently, we have maxArity set to 1024 (the default). This is true for both simpleRestJson clients and servers.

The limit arguably doesn't make as much sense on the client as on the server, because we (hopefully) know whom we're calling, and trust that they're not going to DDOS us - so the default limit should be removed.

I'm not sure how easy it'll be without changing the current APIs, because it'd have to be applied to clients only, and currently the config is shared:

smithy4s/modules/http4s/src/smithy4s/http4s/SimpleRestJsonBuilder.scala

Lines 57 to 62 in 9a12e32

	def withMaxArity(maxArity: Int): SimpleRestJsonBuilder =
	new SimpleRestJsonBuilder(
	simpleRestJsonCodecs.transformJsonCodecs(
	_.configureJsoniterCodecCompiler(_.withMaxArity(maxArity))
	)
	)

The behavior should be:

• SimpleRestJsonBuilder.client(...).build - uses Int.MaxValue
• SimpleRestJsonBuilder.withMaxArity(1024).client(...).build - uses 1024 (current behavior)
• SimpleRestJsonBuilder.routes(...).build - uses 1024
