This pull request introduces support for an HTTPS client device in the shared drivers crate. The main changes add dependencies and code to enable HTTPS communication, as well as expose the new device for use in the system. The most important changes are grouped below:

New HTTPS client device:

• Added a new https_client module and corresponding HttpsClientDevice to drivers/shared/src/devices, and exposed it for use.
• Registered the HttpsClientDevice as a character device at /devices/https_client in the native example, making it available for testing or demonstration.

Dependency updates:

• Added embedded-tls with alloc feature and no default features to the root Cargo.toml to enable TLS support.
• Added several dependencies to drivers/shared/Cargo.toml to support networking, async I/O, TLS, random number generation, and synchronization for the new HTTPS client device.

General codebase changes:

• Added extern crate alloc; to drivers/shared/src/lib.rs to support heap allocations required by the new device and dependencies.
