Official support for C++?

[vikgus1]

Noticed a C lib was in the pipe for 0.29. #993

Will there also be a C / C++ header made available so that we can have official support for PKL in C/C++?

The immediate goal of these C bindings is to be another way for a host language (Go/Swift/Python/TS/etc) to call into Pkl.
It's not really to be a full-fledged language binding, where you have a rich evaluator API, codegen, and such.

However, something like this does enable a richer language binding to C/C++ in the future.

Here's a SPICE to add a C library for Pkl: apple/pkl-evolution#16
