Subject: [PATCH] ANDROID: kleaf: Initial list of ddk_headers (1: arm64)

This CL includes headers used by the external modules of
a typical arm64 device.

Allowlist: This is a list of headers and a list of
include directories that are known to be safe
to be used by modules.

- This list includes:
  - Everything under
    - arch/arm64/include
    - include

Unsafe list: This is the list of headers that are known to be used
by a certain Pixel device kernel build, minus allowlist.

The unsafe list is untouched in this CL because:
- mainline is volatile;
- we don't have ddk_module's for arm64 devices on mainline yet.

The command to generate this list is:

bazel run //build/kernel/kleaf:gen_ddk_headers \
  --gen_ddk_headers_target=//gs/google-modules/soc-modules:slider_modules_install
  -- -k

Manual edits:

- manually deleted changes to all_headers_unsafe

This change is a partial cherry-pick of
14e14cc4e9407783a559b22dffd4bd2062714dd5
