[Bug][TCGC] the bumped parameter in method.operation should not onClient=false

[chunyu3]

When use @clientInitialization to bump a operation parameter to client level. The onClient=false of the parameter in operation.

model clientInitModel
{
    p1: string;
}

@route("/bump")
@clientInitialization(clientInitModel)
interface bumpParameter {
    @route("/op1")
    @doc("bump parameter")
    @post
    @convenientAPI(true)
    op op1(@path p1: string, @query q1: string): void;

    @route("/op2")
    @doc("bump parameter")
    @post
    @convenientAPI(true)
    op op2(@path p1: string): void;
}

expected:
onClient = true

actual:
onClient = false
