[GLUTEN-12597][CORE] Remove unused vendored Substrait proto files and dead
proto-based type derivation (#12598)
Delete four vendored Substrait proto files that carry no live message types
in Gluten and were removed upstream (substrait-io/substrait#952 and #940):
capabilities.proto, function.proto, parameterized_types.proto,
type_expressions.proto. Their generated headers were only referenced by
dangling #include lines in cpp/velox/substrait/SubstraitParser.h (the
substrait::Capabilities/FunctionSignature/ParameterizedType/DerivationExpression
types are used nowhere in the native code), which ar [...]
type_expressions.proto's DerivationExpression had one JVM consumer, the
org.apache.gluten.substrait.derivation package (DerivationExpressionNode,
DerivationExpressionBuilder, BinaryOPNode, DerivationFP64TypeNode). That
package is orphaned (no callers in the producer, native backends, or tests), so
it is removed together with the proto. Upstream expresses output-type
derivation via the ANTLR grammar in the extension YAMLs, not
DerivationExpression protos.
Also remove the deprecated Expression.Enum message and its rex_type oneof
field (10), reserving the number and name to match upstream
(substrait-io/substrait#1086). Expression.Enum is not built by the producer nor
parsed by the Velox/ClickHouse backends; enum function arguments use
FunctionArgument.enum instead.
No functional change. Preparatory cleanup toward rebasing the vendored
proto onto Substrait 0.98.0.
