Fix #20181

    net f64

    entity := json.decode(ShopResponseData, data) or { panic(err) }

    data2 := '{"attributes": {"price": {"net": 1, "_type": "Price"}}}'
    entity2 := json.decode(ShopResponseData, data2) or { panic(err) }


	data3 := json.encode(ShopResponseData{attributes: Attributes{price: Prices([Price{net:1.2}])}})

	entity3 := json.decode(ShopResponseData, data3) or { panic(err) }
	println(entity3)

    println(entity)

Improve and fix json_no_inline_sumtypes flag for sumtypes. Add support for option sumtypes and struct variants in vlib/v/gen/c/json.v.

• Fix bug and simplify code for encoding sumtypes with json_no_inline_sumtypes flag by removing unnecessary else branch (link)
• Use var_data variable instead of val prefix for encoding sumtype variants that are time.Time or other structs to make code more consistent and avoid errors (link)
• Add branch to handle decoding option sumtypes with json_no_inline_sumtypes flag by wrapping variant value in _option_ok call (link)
• Check JSON value type when decoding sumtype variants that are structs and return appropriate type and option wrapping (link, link)
