drivers: move alignment attribute on types for MSVC

Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

net/nfp: fix IPsec data endianness

The algorithm key of the security framework is stored in the u8
array according to big-endian, and the driver algorithm key is
CPU-endian of u32, so it maybe need to convert the endianness order
to ensure that the value assigned to the driver is CPU-endian.

This patch removes the operation of converting IPsec Tx metadata
to big-endian to ensure that IPsec Tx metadata is CPU-endian.

Fixes: 547137405be7 ("net/nfp: initialize IPsec related content")
Fixes: 3d21da66c06b ("net/nfp: create security session")
Fixes: 310a1780581e ("net/nfp: support IPsec Rx and Tx offload")
