Support named CLI flags, physics overrides, and refactor global state.
- **Named CLI Flags**: Replaced standard positional arguments with named flags (`--nstep`, `--nthread`, `--noisestd`, `--noiserate`, `--npoolthread`) and preserved Google-wide flags compatibility (via custom argv compacting and InitGoogle).
- **Physics Option Overrides**: Added support for configuring loaded model settings directly from the command line (`--solver`, `--cone`, `--jacobian`, `--integrator`, `--iterations`, `--tolerance`, `--sleep_tolerance`, `--noslip_iterations`).
- **Encapsulated Thread State**: Consolidated loose global variables and per-thread rollout statistics arrays into a single data structure, `RolloutRunner runner`, simplifying mutli-threaded data boundaries.
- **Readable Physics Options Printing**: Logged configured non-default options dynamically prior to rollout. Enums and active bitmask flags (e.g. disableflags/enableflags) are decoded into friendly strings (e.g., `Sleep : Enabled`).
- **Tests & Docs**: Added testspeed_test.sh running testspeed over dominos.xml to check all overrides, registered shell test target in BUILD and CMakeLists.txt, and updated samples.rst documentation.

This removes the need to load these decoders via mj_loadAllPluginLibraries when using MuJoCo built with CMake. Other plugins are unchanged.

*** Reason for rollback ***
Rolling back obj/stl decoder inclusion as sources due to broken windows build.
*** Original change description ***
Include obj and stl decoder plugins as sources in CMake builds.
This removes the need to load these decoders via mj_loadAllPluginLibraries when using MuJoCo built with CMake. Other plugins are unchanged.

MujocoTest now loads plugins from MUJOCO_PLUGIN_DIR if set.
PluginTest is removed; all tests use MujocoTest directly.
testspeed binary loads plugins from MUJOCO_PLUGIN_DIR.
This is in preparation for moving common asset format parsing (obj, msh, stl, etc.) where we will always want to load those plugins.

This change updates all size-related members within the `mjModel` struct from `int` to `mjtSize`. This allows MuJoCo to handle models with a larger number of elements. Corresponding changes were made to macros, function signatures, and I/O routines to accommodate the new `mjtSize` type.

This CL does not change the default build behavior of MuJoCo. To use single-precision floating-point, build MuJoCo with `-DmjUSESINGLE`.

- Fixed bug in timing of kinematics, was under-reported.
- Moved timing of inertia and collision into respective functions, in preparation for multi-threading.
- Detailed profiling in `testspeed` is always on, removed command-line flag.
- Improved `testspeed` self-documentation.

- mjTIMER_ACCELERATION is not very useful, it's usually very tiny (0.5% for humanoid, 1% for 22humanoids). It basically times a single call to `mj_solveM`.
- Added `mjTIMER_ADVANCE` to time `mj_Euler` and `mj_implicit` (which can be significant).
- Moved `mj_transmission` to `mjTIMER_KINEMATICS` where it belongs (and used to be).
