Remove the 'payload' stuff now that we're just doing IO.
...
This unifies the android and other-linux code paths.
The rationale for just doing IO now is as in the previous commit:
we need the whole process to be run as root, so we don't need to
isolate this particular IO in a separate `su -c` command anymore.

Make sampling work on current Android (no su -c).
...
The `su -c` approach does not work on current Android. It seems that
on current Android, access to /proc and /sys is restricted enough
that in practice, developers profiling on Android are likely running
the whole instrumented process as root anyway, so `su` shouldn't be
needed. (In particular, note that access to /proc/$pid is limited
to members of a `readproc` group).

Build sanitization & Static analysis warning fixes
...
- Wrapping FORCEINLINE & WIN32_LEAN_AND_MEAN definess with ifndef bc other libraries may define it and trigger redefinition warning
- Possibly contentious given tone in the manual (:P) but removing variable shadowing in TracySysTrace.cpp
- Alternate Solution: Add #define TRACY_FORCE_SILENT_WARNINGS toggle-able flag. If flag is enabled, push/pop warning disables that have to be included in client code

Ignore kernel-only stacks.
...
It is common to receive duplicate stack traces for the same timestamp
(and thread), one containing proper user-space stack, and the second one
containing only kernel frames. Discard the second one, as there's no
documentation how this should be interpreted and the kernel stack is
mostly useless.
