__asan_report_* function generates the following warnings while compiling
kernel, add them to the internal header to be aligned with other __asan_*
function prototypes.

mm/kasan/generic_report.c:130:6: warning: no previous prototype for '__asan_report_load1_noabort' [-Wmissing-prototypes]
  130 | void __asan_report_load##size##_noabort(unsigned long addr) \
      |      ^~~~~~~~~~~~~~~~~~
mm/kasan/generic_report.c:143:1: note: in expansion of macro 'DEFINE_ASAN_REPORT_LOAD'
  143 | DEFINE_ASAN_REPORT_LOAD(1);
      | ^~~~~~~~~~~~~~~~~~~~~~~

mm/kasan/generic_report.c:137:6: warning: no previous prototype for '__asan_report_store1_noabort' [-Wmissing-prototypes]
