{rust,rustPackages}_1_98: init at 1.98.1

Neither rust_1_95 nor rust_1_97 is new enough for chromium M154, sadly.

Not-cherry-picked-because: unstable carries only 1.98 but 26.05 multiple

+# New rust versions should first go to staging.
+# Things to check after updating:
+# 1. Rustc should produce rust binaries on x86_64-linux, aarch64-linux and x86_64-darwin:
+#    i.e. nix-shell -p fd or @GrahamcOfBorg build fd on github
+#    This testing can be also done by other volunteers as part of the pull
+#    request review, in case platforms cannot be covered.
+# 2. The LLVM version used for building should match with rust upstream.
+#    Check the version number in the src/llvm-project git submodule in:
+#    https://github.com/rust-lang/rust/blob/<version-tag>/.gitmodules
+
+# Note: The way this is structured is:
+# 1. Import default.nix, and apply arguments as needed for the file-defined function
+# 2. Implicitly, all arguments to this file are applied to the function that is imported.
+#    if you want to add an argument to default.nix's top-level function, but not the function
+#    it instantiates, add it to the `removeAttrs` call below.
