Drop FreeBSD support and remove non-crates.io git dependencies

[Copilot]

The redox_hwio and smbios-lib git forks existed solely to support FreeBSD. Drops FreeBSD support and replaces the scattered git deps with crates.io versions. Also removes the uefi/uefi-services git patches from root Cargo.toml (on top of PR #184).

Dependency changes

• redox_hwio: fully replaced with crates.io 0.1.6 across all targets
• smbios-lib: git deps removed from all individual target sections; a single [patch.crates-io] entry in root Cargo.toml replaces them. The no-std fork remains necessary for UEFI builds until upstream adds no_std support.
• uefi / uefi-services: removed [patch.crates-io] overrides from root Cargo.toml

FreeBSD removal

• smbios.rs: removed FreeBSD SMBIOS entry-point structs, kenv_get(), and the FreeBSD get_smbios() impl
• esrt/mod.rs: removed /dev/efi ioctl-based ESRT reading
• ccgx/hid.rs: removed FreeBSD HID usage_page workaround
• Deleted Cross.toml (FreeBSD cross-compilation config)
• Removed build-freebsd CI job
• Cleaned up flake.nix git dependency hashes for redox_hwio and uefi

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.rs
  • Triggering command: /usr/bin/curl curl -s -A framework-system-tool/1.0 (github.com/FrameworkComputer/framework-system) REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

I don't want to completely remove FreeBSD support, just enough to not depend on forked crates. I will try to add it back later

no that's not what i wanted to do
