For each thread also track number of times scheduled, number of kernel
entries and amount of cycles spent inside the kernel. Also add
core-wide totals for each.

Change benchmark_track_reset_utilisation to take a tcb object parameter
so that the function is more widely applicable.

Create per-node global definitions for utilization variables.
This enables the tracking to more cleanly work on SMP configurations.
As resetting and starting the counters via SysBenchmarkResetLog only
updates the counters of the current thread and idle thread on the
current node it was not possible to accurately record utilization
statistics across multiple nodes. Now each node can have its tracking
independently started, stopped and queried. It is possible to add
additional syscalls in the future for doing this for all nodes in a
single syscall.

All the kernel header files now use pargma once rather than the ifndef,
as the pre-processed C files do not change while header files
are protected with pargma once. This will also solve any naming issues
caused by ifndef.
This commit also converts our own copyright headers to directly use
SPDX, but leaves all other copyright header intact, only adding the
SPDX ident. As far as possible this commit also merges multiple
Data61 copyright statements/headers into one for consistency.
These files can be included normally using libsel4 include paths. This
removes situations where the same file is available under different
include paths due to symlinking into different directory structures.
