Make ring buffer size adjustable. 
If call stack capture is enabled for context switch data, the 64KB buffer is
too small to work without overruns. However, if the default buffer size is
increased, then the maximum locked memory limit is hit.

This change keeps the small buffer size for all the buffers that may be used
without escalated privileges. The context switch buffer is bigger, but it does
not need to obey the limits, as the application is running as root, if it is
to be used.

17855cbac5 Call SymLoadModuleEx for modules loaded after init 
This fixes issue #293. Symbols are not loaded if the module is loaded dynamically after the SymInitialize call.
This may stall the symbol resolver thread a bit the first time a module is loaded.

Add IdentifySamples flag to the protocol. 
On Windows there is no way to distinguish callstack data coming from random
sampling and from context switches. Each callstack timestamp has to be matched
against the context switch data in order to decide its origin. This is
obviously non-trivial.

On some other platforms, the origin information may be available right away,
in which case the process of matching against the context switch data, which
possibly includes postponing callstacks for processing in the future, may be
completely omitted.

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.

54ee3d8a94 Expose TRACY_MANUAL_LIFETIME APIs to C API clients 
These are extremely useful for ecosystems such as Rust. There are a
couple of reasons why:

1. Rust strongly advises against relying on life before/after main, as
   it is difficult to reason about. Most users working in Rust will
   generally be quite surprised when encountering this concept.
2. Rust and its package manager makes it easy to use packages (crates)
   and somewhat less straightforward to consider the implications of
   including a dependency.

   In case of the `rust_tracy_client` set of packages, I currently have
   to warn throughout the documentation of the package that simply
   adding a dependency on the bindings package is sufficient to
   potentially accidentally broadcast a lot of information about the
   instrumented binary to the broader world. This seems like a major
   footgun given how easy is it to forget about having added this
   dependency.

Ability to manually manage the lifetime of the profiler would be a great
solution to these problems.
