n-api: change napi_callback to return napi_value

Change `napi_callback` to return `napi_value` directly instead of
requiring `napi_set_return_value`.

When we invoke the callback, we will check the return value and
call `SetReturnValue` ourselves. If the callback returns `NULL`,
we don't set the return value in v8 which would have the same
effect as previously if the callback didn't call
`napi_set_return_value`. Seems to be a more natural way
to handle return values from callbacks. As a consequence,
remove `napi_set_return_value`.

Add a `napi_value` to `napi_property_descriptor` to support string
values which couldn't be passed in the `utf8name` parameter or
symbols as property names. Class names, however, cannot be symbols
so this `napi_value` must be a string type in that case.

Remove all of the `napi_callback_info` helpers except for
`napi_get_cb_info` and make all the parameters to
`napi_get_cb_info` optional except for argc.

Update all the test collateral according to these changes.
Also add `test/addons-napi/common.h` to house some common macros
for wrapping N-API calls and error handling.

n-api: create napi_env as a real structure

1. We define struct napi_env__ to include the isolate, the last
exception, and the info about the last error.

2. We instantiate one struct napi_env__ during module registration and
we pass it into the FunctionCallbackInfo for all subsequent entries into
N-API when we create functions/accessors/finalizers.

Once module unloading will be supported we shall have to delete the
napi_env we create during module init.

There is a clear separation between public and private API wrt. env:

1. Public APIs assert that env is not nullptr as their first action.

2. Private APIs need not validate env. They assume it's not nullptr.
