x86: clean up the APIC_DEST_LOGICAL logic
Impact: cleanup
The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in
a rather nasty way by re-defining it to zero. That is infinitely
fragile and makes it very hard to see what to code really does in
a given context. The very same constant has different meanings and
values - depending on which subarch is enabled.
Untangle this mess by never undefining the constant, but instead
propagating the right values into the genapic driver templates.

Impact: cleanup
Most subarchitectures want to disable the APIC ESR (Error Status Register),

a bigger system and hence the APIC bus is quite non-standard and weirdnesses
(lockups) have been seen with ESR reporting.
Remove the esr_disable macros and put the desired flag into each
