VAO is not update when change buffer binding

[johanzhu]

Describe the bug
When I change the buffer binding of a mesh, I got gl error: "GL_INVALID_OPERATION : glDrawElements: range out of bounds for buffer" if my new buffer' byteLength is larger.

GLPrimitive.ts line 39
if (!this.vao.has(shaderProgram.id)) {
this.registerVAO(shaderProgram);
}

According to above code, VAO is always get from cache.
VAO should update when mesh binding another new buffer .

To Reproduce
Steps to reproduce the behavior:

1. Using mesh renderer rendering a mesh
2. Using setVertexBufferBinding and setIndexBufferBinding bind new buffer to mesh, and new buffer's byte length is larger.
3. Update sub mesh count.
4. See error: GL_INVALID_OPERATION : glDrawElements: range out of bounds for buffer

Expected behavior
MeshRenderer working well, ant no gl error.
