build: use platform for generic and native builds

The current meson option 'machine' should only specify the ISA, which is
not sufficient for Arm, where setting ISA implies other settings as well
(and is used in Arm configuration as such).
Use the existing 'platform' meson option to differentiate the type of
the build (native/generic) and set ISA accordingly, unless the user
chooses to override it with a new option, 'cpu_instruction_set'.
The 'machine' option set the ISA in x86 builds and set native/default
'build type' in aarch64 builds. These two new variables, 'platform' and
'cpu_instruction_set', now properly set both ISA and build type for all
architectures in a uniform manner.
The 'machine' option also doesn't describe very well what it sets. The
new option, 'cpu_instruction_set', is much more descriptive. Keep
'machine' for backwards compatibility.

config: enable/disable drivers in Arm builds

Add support for enabling or disabling drivers for Arm cross build. Do
not implement any enable/disable lists yet.

Enabling drivers is useful when building for an SoC where we only want
to build a few drivers. That way the list won't be too long.

Similarly, disabling drivers is useful when we want to disable only a
few drivers.

Both of these are advantageous mainly in aarch64 -> aarch64 (or arch ->
same arch) builds, where the build machine may have the required driver
dependencies, yet we don't want to build drivers for a specific SoC.

If enable_drivers is a non-empty list, build only those drivers,
otherwise build all drivers and add them to enable_drivers. If
disable_drivers is non-empty list, build all drivers specified in
enable_drivers except those in disable_drivers.

There are two drivers, bus/pci and bus/vdev, which break the build if
not enabled. Address this by always enabling these if the user disables
them or doesn't specify in their allowlist.

Also remove the old Makefile arm configuration options which don't do
anything in Meson.

build: support KNI cross-compilation

The KNI linux module is using a custom target for building, which
doesn't take into account any cross compilation arguments. The arguments
in question are ARCH, CROSS_COMPILE (for gcc, clang) and CC, LD (for
clang). Get those from the cross file and pass them to the custom
target.

The user supplied path may not contain the 'build' directory, such as
when using cross-compiled headers, so only append that in the default
case (when no path is supplied in native builds) and use the unmodified
path from the user otherwise. Also modify the install path accordingly.

build: add header includes check

To verify that all DPDK headers are ok for inclusion directly in a C file,
and are not missing any other pre-requisite headers, we can auto-generate
for each header an empty C file that includes that header. Compiling these
files will throw errors if any header has unmet dependencies.

For some libraries, there may be some header files which are not for direct
inclusion, but rather are to be included via other header files. To allow
later checking of these files for missing includes, we separate out the
indirect include files from the direct ones.

To ensure ongoing compliance, we enable this build test as part of the
default x86 build in "test-meson-builds.sh".

net/mlx: add static ibverbs linkage with meson

The libibverbs (and libmlx4/5) can be statically embedded
in the shared PMD library, or in the application with the static PMD.
It was supported with make build system in
commit 2c0dd7b69fb0 ("config: add static linkage of mlx dependency").

The same feature is enabled with meson when using pkg-config
(i.e. only if the call to dependency() is successful).
The fallback method for searching library with cc.find_library()
is not supported because the dependencies of the found library
would not be linked (no such info in .a file unlike .so).

The main difference, in meson build system, is the generated .pc file
giving arguments to link DPDK with the application.
Unfortunately the .pc file will not keep memory of the static linkage
option for libibverbs.

build: change ABI versioning to global

As per new ABI policy [1], all of the libraries are now versioned using
one global ABI version. Stable libraries use the MAJOR.MINOR ABI
version for their shared objects, while experimental libraries
use the 0.MAJORMINOR convention for their versioning.
Experimental library versioning is managed globally. Changes in this
patch implement the necessary steps to enable that.

The CONFIG_RTE_MAJOR_ABI option was introduced to permit multiple
DPDK versions installed side by side. The problem is now addressed
through the new ABI policy, and thus can be removed.

[David] For external libraries relying on Makefile, LIBABIVER is
preserved to avoid using DPDK global ABI version.
