Fix renderbufferStorageMultisample: invalid internalformat
Chrome 78 is outputting "INVALID_ENUM: renderbufferStorageMultisample: invalid
internalformat" when running a Qt application after building it for WebAssembly (WASM)
against the Qt 5.13 branch using the Emscripten 1.39.3 (upstream) compiler.
The problem appear to be caused by glRenderbufferStorageMultisample not supporting
GL_DEPTH_STENCIL directly. Instead, GL_DEPTH24_STENCIL8 or GL_DEPTH32F_STENCIL8
should be passed. Keeping the glRenderbufferStorage call as-is.

Reference: https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glRenderbufferStorageMultisample.xhtml
Fixes: QTBUG-80286
