Add a deprecation notice informing users that we will require a C11
compiler from 23.11 release onwards. This requirement was agreed by
technical board to enable use of newer C language features, e.g.
standard atomics. [1]

Deprecation Notices
-------------------
+* C Compiler: From DPDK 23.11 onwards,
+ building DPDK will require a C compiler which supports the C11 standard,
+ including support for C11 standard atomics.
The whole of C11, or just the mandatory parts (+atomics)?
+
+ Please note:
+
+ * C11 is supported from GCC version 5 onwards, and is the default language
version in that release
+ * C11 is the default compilation mode in Clang from version 3.6
+
* kvargs: The function ``rte_kvargs_process`` will get a new parameter
for returning key match count. It will ease handling of no-match case.
