Avoid redefining PRI macros on Linux (#4055)

* Avoid redefining `PRI` macros on Linux

The fixed width 64-bit integer types are defined differently per platform.
Some platforms define it as "long", others define it as "long long". For
consistency, `AZ::u64` or `AZ::s64` is always defined to "long long".
However, this causes problems for formatting those types, because on
platforms where `uint64_t` is a `long`, `PRIu64` gives the wrong format
string for `AZ::u64`. Previously this was fixed by redefining the `PRI`
macros so that they work for `AZ::u64`, but that breaks the ability to
format `uint64_t`.

We could add an AZ-specific version of the `PRI` macros for 64-bit integer
types, but we don't really need to, since they are `long long` on every
platform we support.

 * Use `%ll` for `AZ::u64`
 * Use `PRIu64` for `uint64_t`
