Currently, RTE_* flags are set based on the implementer ID but there might
be some micro arch specific differences from the same vendor
eg. CACHE_LINESIZE. Add support to set micro arch specific flags.

pcap has historically shipped a custom pcap-config binary tool which
does the job of pkg-config. It was never compatible with cross
compilation.
Meson uses it when using dependency(), which then means cross
compilation fails.
Set pcap-config to empty in the meson cross compilation files so
that Meson will not use it, and add a fallback in case
dependency() fails.
libpcap 1.9.0 finally ships a pkg-config file so everything will
work out of the box in the future.

Rather than relying on the target machine architecture, use the
size of a pointer from the compiler to determine if we are 64-bits
or not. This allows correct behaviour when you pass -m32 as a compile
option. It also allows us to use this value repeatedly throughout the
repo rather than continually testing for the sizeof(void*).

By default, the DPAA2_USE_PHYS_IOVA setting with the make build-system
is "y", which is overridden to "n" in the config file specifically for
the arm64-dpaa2-linuxapp-gcc builds. The lack of this setting in meson
builds causes issues for 32-bit build, as the alternative code paths
have compiler warnings e.g. for i686 builds. Therefore we should align
the meson and make settings, setting the value to "true" by default and
overriding it to "false" for dpaa2-specific builds.
