Defer unsafety check for fn with ptr argument
...
That error does not need to be fatal at parse time, because the parser
still understands exactly what was written. We accumulate and emit it
alongside other type errors that might be present in the same function
signature.

Avoid wrapping error message across source lines
...
This makes the source of the message easier to locate for someone using
grep with the full message.
The Linux kernel coding style follows the same approach:
https://www.kernel.org/doc/html/v5.10/process/coding-style.html#breaking-long-lines-and-strings
> never break user-visible strings such as printk messages because that
> breaks the ability to grep for them.

Support raw pointers in cxx::bridge.
...
This allows raw pointers to types to be passed into and out of
cxx::bridge extern "C++" APIs. As normal with raw pointers in Rust,
there are no safety or lifetime guarantees.
Passing a raw pointer into such an API requires that the
function be marked "unsafe".
