[WGSL] Fix uninitialized VisibilityValidator::m_stage member
<https://bugs.webkit.org/show_bug.cgi?id=320319>
<rdar://183260812>
Reviewed by Dan Glastonbury.
The constructor initializes only `m_shaderModule`, leaving the
`m_stage` enum member with an indeterminate value. `validate()`
assigns `m_stage` per entry point before visiting each one, but a
shader module with no entry points never enters that loop, so any
later read of `m_stage` would observe an indeterminate value.
Initialize `m_stage` to `ShaderStage::Vertex`, matching how the
sibling `IOValidator` and `GlobalVariableRewriter` passes default the
same member. This silences the clang static analyzer's
`optin.cplusplus.UninitializedObject` finding.
