Support for hybrid CPU (#166)

Browse source 
* Set CMAKE_C_FLAGS_DEBUG to display warnings during build

CI workflows are reporting warnings. Adding more C flags here help to avoid that.

* Add new types

* Add set_cpu_affinity function

* Add cpu_identify_all function

* Add cpu_request_core_type function

* Add cpuid_get_all_raw_data, cpuid_serialize_all_raw_data and cpuid_deserialize_all_raw_data functions

* Detect hybrid architecture for Intel CPUs

* Update cpuid_tool to detect all CPU logical cores

* Rename tests subdirectories for Intel Core

* Update all tests

Since e4309a6c4bc3ad875711a1599cba01a205b3103e, new fields are reported by cpuid_tool

* Add Intel Alder Lake

Fix #157

* Remove convert_instlatx64.c

This tool is not useful anymore because the cpuid_deserialize_raw_data_internal() function can natively parse them since 5667e1401c

* Fix affinity_mask computation

* Define _GNU_SOURCE in configure.ac

Forgotten in 4f80964db5

* Use dynamic raw array in cpu_raw_data_array_t

* Add cpu_affinity_mask_t type

* Improve set_cpu_affinity function

- Print a warning if logical CPU number is not supported on operating system
- Return a boolean value in case of success instead of an integer

* Improve cpu_identify_all and cpu_request_core_type functions

* Use dynamic array for cpu_types in system_id_t

This commit also adds cleanups, fixes and consistency

* Tests: update Ryzen 5 Matisse with all CPU cores

* Add affinity_mask_str_r function and address other comments

- Fixed cpuid_grow_raw_data_array and cpu_raw_data_array_t.logical_cpu_t with the correct type
- Added a note about hard limit of cpu_raw_data_array_t
- Fixed a typo in cpuid_deserialize_raw_data_internal

* Fix build on Windows
