use C linkage where appropriate in headers

Assure that 'extern "C" { /../ }' do not cover files included from a
particular header file, and address minor issues resulting from this
change of order.

Dealing with C++ should delegate to the individual include file level,
rather than being imposed by the user of that file. For example,
forcing C linkage prevents __Generic macros being replaced with
overloaded static inline functions in C++ translation units.

Eliminate 'extern "C"' from files which do not declare any symbols
(e.g., only macros or struct types).

On the other hand, the headers check is too naive in assuming that all
headers must contain a 'extern "C"'. Such a check was added in commit
1ee492bdc4ff ("buildtools/chkincs: check missing C++ guards").
Since this current change results in many headers not containing such
a token, remove the check for 'extern "C"' until we have a better
implementation.

lib: move alignment attribute on types for MSVC

The current location used for __rte_aligned(a) for alignment of types
is not compatible with MSVC. There is only a single location accepted
by both toolchains.

The standard offers no alignment facility that compatibly interoperates
with C and C++ but it may be achieved by relocating the placement of
__rte_aligned(a) to the aforementioned location accepted by all currently
supported toolchains.

To allow alignment for both compilers, do the following:

* Expand __rte_aligned(a) to __declspec(align(a)) when building
with MSVC.

* Move __rte_aligned from the end of {struct,union} definitions to
be between {struct,union} and tag.

The placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for all of GCC, LLVM, MSVC compilers building both C and C++.

Note: this move has an additional benefit as Doxygen is not confused
anymore like for the rte_event_vector struct definition.

Packed and Split layout support is added in the specification.

Updated rte_ml_op to support array of rte_ml_buff_seg
pointers to support packed and split I/O layouts.
Updated ML quantize and dequantize APIs to support rte_ml_buff_seg
pointer arrays.
Replaced batch_size with min_batches and max_batches in rte_ml_model_info.

Implement support for model IO layout in ml/cnxk driver.
Updated the ML test application to support IO layout and
dropped support for '--batches' in test application.

This change is a preparatory step for revised xstats APIs.
Revised xstats APIs support reporting device and per model
stats, which is based on eventdev xstats.

Removed xstats APIs from spec and library implementation.
Disabled reporting xstats in test application and disabled
xstats functions in drivers. Renamed stats_get function to
throughput_get.

This change is needed as the revised APIs are not backward
compatible with the current xstats.
