[PATCH v1 08/11] perf annotate-data: missing <string.h> inclusion for libc string functions

[Ian Rogers]

Sashiko reported:

  When compiling the perf tool with musl libc,
  tools/perf/util/annotate-data.c fails to build due to the missing
  <string.h> header.

  The source file utilizes standard C library string and memory
  functions, such as memset() in init_type_state() and strcmp() in
  data_type_cmp(). While glibc implicitly pulls in <string.h> via
  other standard headers, musl libc enforces stricter header
  separation. Because the header is not explicitly included at the top
  of the file, the compiler encounters implicit function declarations
  for these standard string functions. This results in a direct
  compile-time build error.

Add the header files and use git clang-format to sort.
