Implement MSG_WAITALL flag for stream sockets. Setting this flag on
`recv()` call will make it wait until the requested amount of data is
received.
In case both, MSG_WAITALL all is set and SO_RCVTIMEO option configured
on a socket, follow the Linux behavior, i. e. when the requested amount
of data is not received until the timeout expires, return the data
received so far w/o an error.

There exist zsock_ counterparts of the two mentioned
functions, but they were not exposed in the Zephyr POSIX API
(CONFIG_POSIX_API=y). This commit fills the gap.

Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.
Background from issue #17997:
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

A few of these headers are currently empty and provided to avoid
compiler errors when building existing software.
This set of headers is what is required to build
https://github.com/open62541/open62541 with Zephyr.
