852a1a5f14 Add TracyIsStarted
When using TRACY_MANUAL_LIFETIME, calling most Tracy functions
before starting the profiler results in an assertion. Notably, even
TracyIsConnected is affected. There is, however, no function to check if
the profiler had already started. This commit adds such a function.

5417227e83 Use patchable rdtsc sequence to avoid slowdowns under rr
We (Julia) ship both support for using tracy to trace julia applications,
as well as using `rr` (https://github.com/rr-debugger/rr) for record-replay debugging.
After our most recent rebuild of tracy, users have been reporting signfificant performance
slowdowns when `rr` recording a session that happens to also load the tracy library
(even if tracing is not enabled). Upon further examination, the recompile happened
to trigger a protective heuristic that disabled rr's patching of tracy's use of
`rdtsc` because an earlier part of the same function happened to look like a
conditional branch into the patch region. See https://github.com/rr-debugger/rr/pull/3580
for details. To avoid this issue occurring again in future rebuilds of tracy,
adjust tracy's `rdtsc` sequence to be `nopl; rdtsc`, which (as of of the
linked PR) is a sequence that is guaranteed to bypass this heuristic
and not incur the additional overhead when run under rr.

This functionality is kept behind a compile-time flag `TRACY_PATCHABLE_NOPSLEDS`
in order to avoid polluting the instruction cache unnecessarily.

e1b1fd72dc Wrap std::numeric_limits<T>::max() in parenthesis
The windows.h header file defines the macro max. If the max macro is include
it will lead to name collisions with the std::numeric_limits<T>::max() function.

One solution is to define NOMINMAX before the inclusion of windows.h.
However, that might be a demanding task for a large codebase. Defining the
NOMINMAX as global define may also break previous code.

Another to solution to the problem is to wrap the numeric_limits function in
parenthesis to instruct the compiler to treat it as a function and not a macro.

This commit wraps the std::numeric_limits<T>::max() calls in the public
interfacing header files, with parenthesis.

Fix message color component names in the protocol.
Red and blue channels were mislabeled. Otherwise, coding and decoding was
performed correctly, as far as the color channel order described in the manual
is followed by the user.

No change to the binary protocol was made.

Decouple source code retrieval from the profiler thread.
This will prevent apparent freezes of the profiler when debuginfod queries are
made.
