The `rust_print` module, when built as a module, fails to build with:
ERROR: modpost: missing MODULE_LICENSE() in samples/rust/rust_print_events.o
ERROR: modpost: "__tracepoint_rust_sample_loaded" [samples/rust/rust_print.ko] undefined!
ERROR: modpost: "rust_do_trace_rust_sample_loaded" [samples/rust/rust_print.ko] undefined!
Fix it by building it as a combined one.

This updates the Rust printing sample to invoke a tracepoint. This
ensures that we have a user in-tree from the get-go even though the
patch is being merged before its real user.

We also remove the `try_` prefix to align with how `Box` and `Vec` are
providing methods now.
`init` is temporarily updated with uses of GFP_KERNEL. These will be
updated in a subsequent patch to take flags as well.

This both demonstrates the usage of different print format in Rust and
serves as a selftest for the `Display` and `Debug` implementation of
`Arc` and its friends.

Instead of taking binary string literals, take string ones instead,
making it easier for users to define a module, i.e. instead of
calling `module!` like:
module! {
...
name: b"rust_minimal",
...
}
now it is called as:
module! {
...
name: "rust_minimal",
...
}
Module names, aliases and license strings are restricted to
ASCII only. However, the author and the description allows UTF-8.
For simplicity (avoid parsing), escape sequences and raw string
literals are not yet handled.

Add example to exercise the printing macros (`pr_*!`) introduced
in the previous patches.
