f2b0aadedc Return external names, instead of sending them. 
Note that the old function is still used by code, so this commit won't
compile.

250ef2cf6e Change thread id size from 64 to 32 bits. 
Both Windows and Linux use 32-bit thread identifiers. MacOS has a 64-bit
counter, but in practice it will never overflow during profiling and no false
aliasing will happen.

These changes are only done client-side and in the network protocol. The
server still uses 64-bit thread identifiers, to enable virtual threads, etc.

789328f73d Undo my previous change. 
-D_WIN32_WINNT=0x601 must be defined when building TracyClient.cpp for mingw-w64 on Windows. In that case definitions I've added are not needed.

233a0bb6d6 Set precise_ip to 0 for cache on Intel. 
Fuck knows how this is supposed to work. perf_event_open() opens the
descriptor successfully, but it produces no samples, if precise_ip is not 0.
There are no such problems on ARM (where precise_ip is 3, but maybe it is not
supported at all on that architecture, again, fuck knows if), and on AMD
perf_event_open() does not succeed when precise_ip > 0.
