[WebGL] Harden texImageImpl byte length calculation
rdar://98583503
Reviewed by Kimmo Kinnunen and Ryan Haddad.
The calculation of the image size has been validated earlier but out of an
abundance of caution, use checked arithmetic on size_t to perform
calculation,
returning a GL error on overflow.
* Source/WebCore/html/canvas/WebGLRenderingContextBase.cpp:
(WebCore::WebGLRenderingContextBase::texImageImpl):
Calculate imagePixelsByteLength with checked arithmetic to catch integer
overflow.
