This in preparation for an upcoming change that uses native file dialogs instead
of our very basic ImGui file dialog.

Update SetFrameBuffer to allow users to customize which swap chain
(window or offscreen) to use for rendering both the main mjvScene
as well as the GUI.

Resource operations (e.g. mju_openResource, mju_readResource, and
mju_closeResource, etc.) are now all handled by a VFS instance. It
is now up to the VFS to determine which provider to use in order to
handle those operations.
This allows us to dynamically add/remove (aka "mount") providers to
a VFS to handle special requests. mj_addFileVFS and mj_addBufferVFS
have been reimplemented as two such use-cases. Moreover, we expose
the mounting behaviour with two new functions: mj_mountVFS and
mj_unmountVFS.

The dense Jacobian arrays `J0_dense` and `J1_dense` are now zeroed only once before the vertex loop. Inside the loop, only the entries that were actually used are zeroed out after being added to the sparse Jacobian, allowing for efficient reuse of the dense arrays across all vertices.

Use unsigned size_t instead of signed mjtSize for size multiplications to avoid Clang's overflow-checking intrinsic. This is semantically correct as size calculations are inherently unsigned.

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 change adds an Emscripten binding for loading binary MuJoCo models (`.mjb`) from the virtual filesystem. The new binding, `mj_loadBinary`, takes a filename and an `MjVFS` object, enabling the loading of models that reference assets within the VFS.

There are three ways to load a model: from a file, from a buffer, or an
"empty" model. Instead of overloading a single function to do all three,
provide three separate functions.
Also disable model loading functions that will not work for emscripten.

The ImGui table API cell padding variables can be used to adjust the positioning of the UI in the box.

This change introduces two new USD API schema:
* MjcEqualityAPI - base API for representing MuJoCo equality constraints in USD, this will typically be applied to joints such as UsdPhysicsFixedJoint.
* MjcEqualityWeldAPI - extends MjcEqualityAPI for MuJoCo's weld equality constraints with an attribute for torqueScale.
The usd_decoder is updated to parse UsdPhysicsFixedJoints and convert the new schema attributes into the appropriate mjsEquality data fields.
