Support context parameters

[rnett]

Is your feature request related to a problem? Please describe.
Using a context parameter currently causes a compiler exception.

Describe the solution you'd like
Context parameters are supported, just like value parameters.

Describe alternatives you've considered
Not supporting context parameters. Why, though? They are a useful part of the language.

Additional context

Code:

@Rpc
interface ToolTestService {
    @McpTool(
        "basic_tool",
        description = "A basic tool",
        title = "Basic Tool",
        readOnlyHint = true,
        destructiveHint = false,
        idempotentHint = true,
        openWorldHint = false,
    )
    suspend fun basicTool(): String

    @McpTool(
        "context_tool"
    )
    context(ctx: McpRequestContext)
    suspend fun contextTool(): String

    object Impl : ToolTestService {
        override suspend fun basicTool(): String = "test"

        context(ctx: McpRequestContext)
        override suspend fun contextTool(): String {
            return "context"
        }
    }
}

You can ignore the @McpTool annotations, they do not influence the compiler.

Hey @rnett ! Thanks for the ticket
We didn't yet had time to support it (and it is a bit tricky), but we'll do so
