This patch defines ASAN_SHADOW_OFFSET for arm64 according to the ASan
documentation. This offset should cover all arm64 VMAs supported by
ASan.

This patch adds necessary hooks in the memory allocator for ASan.
This feature is currently available in DPDK only on Linux x86_64.
If other OS/architectures want to support it, ASAN_SHADOW_OFFSET must be
defined and RTE_MALLOC_ASAN must be set accordingly in meson.

AddressSanitizer [1] a.k.a. ASan is a widely-used debugging tool to
detect memory access errors.
It helps to detect issues like use-after-free, various kinds of buffer
overruns in C/C++ programs, and other similar errors, as well as
printing out detailed debug information whenever an error is detected.
ASan is integrated with gcc and clang and can be enabled via a meson
option: -Db_sanitize=address
See the documentation for details (especially regarding clang).
Enabling ASan has an impact on performance since additional checks are
added to generated binaries.
Enabling ASan with Windows is currently not supported in DPDK.
