[roll third_party/pigweed] targets/android: Generic Android target

This creates a Pigweed target for a generic Android device built
against a downloaded Android NDK, the path of which is specified in
the `pw_android_toolchain_NDK_PATH` build arg.

Toolchains for all four supported CPU types (arm, arm64, x64, x86) are
generated, so this can be used with e.g.:

  pw_executable("hello") {
    sources = [ "hello.cc" ]
    deps = dir_pw_log
  ]

  group("android_apps") {
    deps = [
      ":hello(//targets/android:arm_android_debug)",
      ":hello(//targets/android:arm64_android_debug)",
    ]
  }
