wangmingrong1 469418f3c9 mm/kasan: Kasan global support setting alignment length 
1. Similar to asan, supports single byte out of bounds detection
2. Fix the script to address the issue of not supporting the big end

wangmingrong1 071af0c993 mm/kasan: Tag kasan and generic kasan use the same instrumentation options 
1. Tested on QEMU, the two sockets were basically the same, and their performance was not affected. The size of the generated bin file was also the same
2. Extract global detection as a separate file, both types of Kasan support global variable out of bounds detection simultaneously

wangmingrong1 5c511443fe mm/kasan: Using arrays instead of linked lists 
1. Modify the Kasan global variable script to support array storage of region addresses
2. Due to the lack of formatting in the previous attempt, a formatting script was created
