Add functionality to identify the CPU vendor and features using the CPUID instruction. The CPU vendor information is stored in the Processor Control Block (PRCB), including the vendor name and a corresponding enumeration. CPU features are also retrieved and stored in the PRCB. Previously, the CPU vendor was not properly stored in the PRCB, caused by a missing type cast. Using Rtl functions to copy the CPU vendor name to the PRCB. Details: - Introduced functions `ArpSetCpuVendor` and `ArpSetCpuFeatures` to set CPU vendor and features, respectively. - Modified `ArpIdentifyProcessor` to call the new functions for vendor and features identification. - Added `CPU_FEATURES` structure to `KPROCESSOR_CONTROL_BLOCK` structure to store CPU features. Tests: - Tested x86_64 on QEMU. Verified that the CPU vendor and features are correctly identified and stored in the PRCB.
