[C++] Add a struct_ overload taking a vector of (name, type) pairs

[pitrou]

Describe the enhancement requested

It would be nice to be able to write:

 struct_({{"a", int8()}, {"b", utf8()}});

instead of:

 struct_({field("a", int8()), field("b", utf8())});

Same with the schema factory.

I can take this issue if no one has started working on it yet.

@jsjtxietian Yes, you can submit a PR if you want.

@pitrou Hi，I have a question regarding this issue and I want to ask for your advice.

In this code, because field is a function with default parameters, one can pass not only name and type to this function, but also nullable and metadata
struct_({field("a", int8()), field("b", utf8())});

but in the following form, I can use std::initializer_list<std::pair<std::string, std::shared_ptr>> as the input parameter, but in this way it's hard to add support for passing in nullable and metadata conveniently like the field function. std::tuple doesn't support default parameters too.
struct_({{"a", int8()}, {"b", utf8()}});

I guess there is a better way to write this overload function or shall we just support (name, type) pairs for now?
Thanks for your time.

We can just support (name, type) pairs since that's the common case anyway.
