[Test] (Pipe): pin the P1 poison and verify shapes - 63 fields, 69 verbs, the seven sticky fields, an omitted GenerateMipmap field leaves exactly that field stale, a corrupted snapshot names its field, reading an unfilled field aborts with SIGABRT

- PipeCatalogueTest (header-only, every build): VerbTableIsTheFunctionTable (69 verbs, 9 non-empty classes, the seven sticky bits in every class mask, D7's edges), StickyFieldsAreExactlyTheSeven, FloatVectorsCompareBitwise (a NaN FloatVec4 equals itself, -0.0f differs from 0.0f, a differing BlendStates[3] names RenderState then BlendStates), SixValueStructsHaveFieldLists (69 payloads, PixelStoreParameters and MGHostSpan compared member-wise with Pad0 ignored).
- PipeInputsTest, a new unit target linking the static library with its own main() that points MOBILEGL_LOG_FILE_PATH at a temp file: a fake GLContext, the real filler and accessors. OmittingOneFieldForOneVerbLeavesExactlyThatFieldStale (G5 layer 1), ReadingAnOmittedFieldAbortsNamingTheVerb (G5 layer 2: fork, the child reads the omitted field after a draw and a sibling read that must not abort, the parent expects SIGABRT and the exact Fatal line and no @DrawArrays), ReadingAFilledFieldCompletes (the sibling without the omission: _exit(0), no Fatal), CorruptedSnapshotFieldIsNamedWithItsSerial (G4 at block level: clean compare true, a corrupted GetRenderStateParameters is named, its stamp is the fill serial, a corruption outside the mask is not seen), EveryVerbFillsItsClassAndNothingElse (after each of the 69 fills a field is fresh iff its class bit is set).
- Every PipeInputsTest case is a visible GTEST_SKIP in a pull build and the poison/verify cases skip in a push build without them; the ctest name set is the same in all three configurations (additions only: 9 names).
