Remove wxGraphicsContext test (not needed for KiCad WASM)

KiCad uses OpenGL GAL directly via WebGL, completely bypassing
wxGraphicsContext. The graphicsctx test app was crashing because
GetDefaultRenderer() returns NULL when wxUSE_CAIRO=0.

Since KiCad's rendering doesn't use wxGraphicsContext, this test
is unnecessary. Updated WHATWORKS.md to document this finding.

Test count: 246 -> 240 (34 apps)
