🚧 Refactor CI workflows to use Conan 2.23.0 and consolidate builds (#98)

Upgrade default Conan version from 2.16.1 to 2.23.0 across workflows
and streamline the setup process by replacing manual remote/profile
configuration with the new `conan hal setup` command.

Consolidate individual Cortex-M architecture jobs into two unified
jobs (LLVM and GCC) using a new baremetal_package.sh script that
builds all architectures sequentially. This reduces workflow
complexity from 14+ separate jobs to 2 consolidated jobs while
maintaining support for all Cortex-M variants (M0, M0+, M1, M3, M4,
M4F, M7F, M7D, M23, M33, M33F, M35PF, M55, M85).

Add modules_support_needed flag to control GCC build execution,
since GCC doesn't currently support C++ modules.

Update compiler profile references from versioned hal/tc/arm-gcc-12.3
to unversioned hal/tc/arm-gcc for better maintainability.
