* export proper syntax for GSL_SUPPRESS for new VS (#1213)

A new Visual Studio version will soon be available that deprecates the
old syntax for gsl::suppress. Customers will now get a C4875 diagnostic
on suppressions that look like `gsl::suppress(x)` urging them to use
`gsl::suppress("x")` instead.

This change updates the `GSL_SUPPRESS` macro to preprocess
GSL_SUPPRESS(x) to gsl::suppress("x") on clang and new versions of MSVC.

* Revert unintended change to GSL_SUPPRESS (#1226)

PR #1213 changed this line. According to https://github.com/microsoft/GSL/pull/1213/files#r2586073058 the change was unintended. This PR reverts the change to the previous implementation.
