When gcc is building without -fno-builtin, it will optimize calls like
printf("\n") into a call to putchar('\n'), but it won't use a static inline
in that case, instead insisting on a real function.
To make this a bit easier, adopt the usual C library practice of making
putc and putchar macros instead of static inline functions. There's no loss
of typechecking as the parameters are directly passed to underlying
functions with the same parameter types.

In order to bring consistency in-tree, migrate all lib code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

This lets the toolchain header files determine how to use "restrict"
instead of having that decision down in the minimal libc library.

Add __printf_like attribute to printf style functions in minimal libc to
enable the compiler checking this provides. We fixup the associated
issues that are now found by utilizing these checks.

As it turns out Xtensa SDK headers also define _Restrict, causing
havoc. As this was intended to be a private macro, rename it to something
less likely to cause a collision.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

According to commit b71a8a4591 and Jira: ZEP-733
(libc: remove stddef.h which is provided by the compiler),
the stddef.h in zephyr code is removed and it's provided
by the compiler. The original stddef.h includes two head
files, null.h and size_t.h, which are also useless now.
So remove these two deprecated files, in case conflicting
definition.

Updates the minimal libc headers for differences between the C and C++
languages. This includes ...
1. Conditionally defining "bool", "true" and "false" as they are
already keywords in C++.
2. Making the definition of NULL language dependent.
3. Using the _Restrict macro instead of the restrict keyword as
restrict exists in C, but not in C++.
4. Changing the definition of size_t so that it is compatible with
what the compiler expects when building the new operator stubs
(as it varies by architecture).
