sys: add conf/std.debug, generic debugging options

The new sys/conf/std.debug contains the list of debugging options
enabled by default in -CURRENT, so they don't need to be listed
individually in every kernel config.

The enabled options are the set of all debug options which were enabled
for the GENERIC kernel on any platform. This means some architectures
now have debugging options enabled in GENERIC which weren't previously
enabled:

- amd64: [1]
- arm64: [2]
- arm: [2]. [3]
- i386: [1], [2]
- powerpc: [1], [2], [3]
- riscv: [2]

[1] ALT_BREAK_TO_DEBUGGER is now enabled.
[2] BUF_TRACKING, FULL_BUF_TRACKING, and QUEUE_MACRO_DEBUG_TRASH are now
enabled.
[3] DEADLKRES is now enabled.

While here, move the documentation for the (commented out) K*SAN options
for amd64 from GENERIC to NOTES.

Xen's EFI support is also quite troublesome on non-x86. This is being

should be disabled.

net80211: fix IEEE80211_DEBUG_REFCNT builds

Remove the KPI/KBI changes from ieee80211_node.h and always use the
macros to pass in __func__ and __LINE__ to the functions.
The actual implementations are prefixed by "_" rather than suffixed
by "_debug" as they no longer are "debug"-specific.

Some of the select functions were not actually using the passed in
func, line options; however they are calling other functions which
use them. Directly call the internal implementation in those cases
passing the arguments on.

Use a file-local __debrefcnt_used define to mark the arguments __unused
in cases when we compile without IEEE80211_DEBUG_REFCNT and hope the
toolchain is intelligent enough to not pass them at all in those cases.

Also _ieee80211_free_node() now has a conflict so make the previous
_ieee80211_free_node() the new __ieee80211_free_node().

Add IEEE80211_DEBUG_REFCNT to the NOTES file on amd64 to keep exercising
the option.
