6249999153 linux: respect TRACY_NO_SAMPLING for sys-tracing
This compile-time flag was being ignored on Linux. This change adds
gating for software-sampled stack trace sampling following the same
pattern as other `TRACY_NO_SAMPLE_*` options.

If `TRACY_NO_SAMPLING=1` is provided as an environment variable,
software stack sampling is also disabled.

789f572332 Fix compilation on linux: use abort() instead of assert( false ).
assert() in release configuration resolves to empty code, while abort() is marked as [[noreturn]] and always is available.

gcc error:

ece8779362 Fix cpuid symbol redefinition on older GCC versions
Since commit 940f32c1a8 building the Tracy
library on Linux using a GCC version < 11 would result in compile errors
due to symbol redefinitions of __get_cpuid_max, __get_cpuid and
__get_cpuid_count.

This is because prior to GCC 11 the cpuid.h header file did not have any
include guards and thus including this header more than once would
produce the abovementioned errors.

To work around this issue, including cpuid.h has been wrapped into a
custom header file that itself uses include guards and thus shields
cpuid.h from being included multiple times.

Fixes #452

Keep a list of buffers left to handle.
Previously a bitmap of buffers was repeatedly scanned to see which buffers
still contain data. This process was needlessly wasting cycles (seen as a
hotspot when profiled) and worse yet, the workload increased with the number
of CPU cores (=> buffers used) to handle.

The new implementation instead maintains a list of buffer indices that have to
be handled. This list does not contain empty buffers, so each loop iteration
performs some work, instead of just spinning in search for buffers to handle.
