Andy Ross 77719b81e9 arch/xtensa: Clean up fatal error handling
Update the xtensa backend to work better with the new fatal error
architecture.  Move the stack frame dump (xtensa uses a variable-size
frame becuase we don't spill unused register windows, so it doesn't
strictly have an ESF struct) into z_xtensa_fatal_error().  Unify the
older exception logging with the newer one (they'd been sort of glomed
together in the recent rework), mostly using the asm2 code but with
the exception cause stringification and the PS register field
extraction from the older one.

Note that one shortcoming is that the way the dispatch code works, we
don't have access to the spilled frame from within the spurious error
handler, so this can't log the interrupted CPU state.  This isn't
fixable easily without adding overhead to every interrupt entry, so it
needs to stay the way it is for now.  Longer term we could exract the
caller frame from the window state and figure it out with some
elaborate assembly, I guess.

Fixes #18140

Andrew Boie 96571a8c40 kernel: rename NANO_ESF
This is now called z_arch_esf_t, conforming to our naming
convention.

This needs to remain a typedef due to how our offset generation
header mechanism works.

Kumar Gala cc334c7273 Convert remaining code to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies.  We also convert the PRI printf formatters in the arch
code over to normal formatters.
