Description

This PR bumps the Minimum Supported Rust Version (MSRV) from Rust 1.70 to 1.76.

This PR includes the following changes:

• Bumps MSRV to 1.76.0.
• Move lint configuration to workspace level [lints] table and removes the .cargo/config.toml file.
• Updates CI workflows to handle the removal of the .cargo/config.toml file.
• Removes unnecessary #![forbid(unsafe_code)] annotations in crates.
• Removes unused main.rs file in the analytics crate.
• Enables clippy warnings on usages of println!() and eprintln!() with the clippy::print_stdout and the clippy::print_stderr lints, respectively.
• Removes the unused static_cache module in the common_utils crate.
• Updates some usages of map_err() which returned the original error with inspect_err().

Motivation and Context

Bumping MSRV allows us to take advantage of the new features introduced and functions / methods stabilized between Rust 1.70 and 1.76. Some of the features / functions include:

• Lint configuration in Cargo.toml: Our previous lint configuration was done via setting RUSTFLAGS in .cargo/config.toml, which re-compiles all crates if we introduce a new lint.
• Result::inspect, Result::inspect_err and Option::inspect.
• type_name_of_val

In addition, this would also allow us to update some of our dependencies to newer versions.
