Introduce chiseled Docker image

[rubo]

Resolves #6567

Changes

This PR introduces an additional chiseled rootless Docker image for enhanced security: Dockerfile.chiseled

As chiseled images don't support package managers to install Snappy required by some of Nethermind components, those components have been updated not to require Snappy installation as follows:

• The obsolete Snappy.Standard package that provides bindings for the native Snappy library has been replaced with the newer Snappier package implemented in C#
• The RocksDB package has been replaced with Nethermind.RocksDB.Runtimes package that uses the official binaries from Meta that don't require Snappy installation
• The release workflow now builds two images -- regular and chiseled
• All Snappy dependencies have been removed from the codebase

These changes greatly simplify Nethermind installation and docs, eliminating any prerequisites that are especially annoying for RHEL-like distros.
