eal: remove number of cpuflags from API
The RTE_CPUFLAG_NUMFLAGS enum value was mainly a canary for internal
use. Yet, it could be passed by an application to
rte_cpu_get_flag_enabled() / rte_cpu_get_flag_name().
So, even though passing this value to those functions is debattable,
changing its meaning (by adding a new CPU feature for example) would
impact ABI compatibility.
This patch removes RTE_CPUFLAG_NUMFLAGS to avoid such future ABI
compatibility issue.

eal/loongarch: support LoongArch architecture
Add all necessary elements for DPDK to compile and run EAL on
LoongArch64 Soc.
This includes:
- EAL library implementation for LoongArch ISA.
- meson build structure for 'loongarch' architecture.
RTE_ARCH_LOONGARCH define is added for architecture identification.
- xmm_t structure operation stubs as there is no vector support in
the current version for LoongArch.
Compilation was tested on Debian and CentOS using loongarch64
cross-compile toolchain from x86 build hosts. Functions were tested
on Loongnix and Kylin which are two Linux distributions supported
LoongArch host based on Linux 4.19 maintained by Loongson
Corporation.
We also tested DPDK on LoongArch with some external applications,
including: Pktgen-DPDK, OVS, VPP.
The platform is currently marked as linux-only because there is no
other OS than Linux support LoongArch host currently.
The i40e PMD driver is disabled on LoongArch because of the absence
of vector support in the current version.
Similar to RISC-V, the compilation of following modules has been
disabled by this commit and will be re-enabled in later commits as
fixes are introduced:
net/ixgbe, net/memif, net/tap, example/l3fwd.
