powerpc architecture (both 64-bit and 32-bit) supports stack protector
mechanism since some time now [see commit 06ec27aea9fc ("powerpc/64:
add stack protector support")].
Update stackprotector arch support documentation to reflect the same.

HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation. It is not about the compiler support.
For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.
I moved the 'select' lines to keep the alphabetical sorting.

Now that the script 'features-refresh.sh' is available, uses this script
to refresh all the arch-support.txt files in place.

A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.
We already removed the lines for metag and mn10300, this does
the same edits for all the others.
For the remaining 21 architectures, this shows how many are known
to implement each given feature:

need to be added.

The implementation is adopted from the ARM arch. GCC 7.3, 8 or newer is
required for building the xtensa kernel with SSP.

hence remove all references to it from Documentation.
