Adjust function definitions in kern_dtrace.c to avoid clang 15 warnings

With clang 15, the following -Werror warnings are produced:

sys/kern/kern_dtrace.c:64:18: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
kdtrace_proc_size()
^
void
sys/kern/kern_dtrace.c:87:20: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
kdtrace_thread_size()
^
void

This is because kdtrace_proc_size() and kdtrace_thread_size() are
declared with (void) argument lists, but defined with empty argument
lists. Make the definitions match the declarations.

sys/kern: adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Sprinkle __read_frequently on few obvious places.

Note that some of annotated variables should probably change their types
to something smaller, preferably bit-sized.

No FreeBSD version bump, the userland application to query the features will

needed.

data via ctor and dtor event handlers.

The size of the extra data is allocated opaquely and this file
contains a function which the dtrace module can call to check
that the kernel supports at least the amount of data that it needs.

This file is optionally compiled into nthe kernel if the KDTRACE_HOOKS
kernel option is defined.
