Marked every published ThreadX include directory as SYSTEM so applications no longer get warnings from ThreadX headers (#713)

* Marked every published ThreadX include directory as SYSTEM so applications no longer get warnings from ThreadX headers

Commit 8c3c08f added the SYSTEM keyword to the target_include_directories
call in common/CMakeLists.txt, but the same call in every port, in the
SMP common directory's consumers, in the POSIX and FreeRTOS compatibility
layers, and for the generated tx_user.h directory was left unchanged.
A consumer building with a strict warning set therefore still saw
diagnostics coming from tx_port.h and from the compatibility layer
headers, which is exactly what the original change set out to avoid.

Added the SYSTEM keyword to all of those calls so CMake emits -isystem
rather than -I for every directory holding a ThreadX public header. The
ARMv7-M, ARMv8-M, ARMv7-A and ARMv8-A architecture sources under
ports_arch were updated alongside the ports they generate, keeping the
two in step.

Directories that are PRIVATE to an example or test build were left as
they are, since nothing is published from them.

Fixes #290

* Stopped apt-get update being a gate it was never meant to be

apt-get update fails if any configured repository serves a bad index,
including ones this project never reads. The GitHub runner image carries
Google's and Microsoft's apt repositories, and a Hash Sum mismatch from
Google's, their CDN caught mid-publish with the index and the Release
file eight hours apart, failed all three attempts and turned a run red
over a browser nobody was installing.

Made a failed update warn and carry on, leaving apt-get install as the
gate. Nothing is weakened by that: the install still exits on a package
it cannot find, so an unreachable archive still stops the script, one
step later and naming the package it could not get, which is a better
diagnostic than a hash mismatch in a repository nobody asked for.

Disabling third-party sources before updating would keep the update
strict, but this script also runs on a contributor's own machine, and
rewriting someone's apt configuration to suit CI would be worse than
tolerating a stale index for an archive we do not read.
