Closes duckdb/ducklake#977 When I was using DuckLake I met certain issue ```sh memory D ATTACH ':memory:' AS dl (TYPE ducklake, DATA_INLINING_ROW_LIMIT 1000); memory D CREATE TABLE dl.test(id INTEGER, val TEXT); memory D INSERT INTO dl.test VALUES (1, 'a'), (2, 'b'), (3, 'c'); memory D BEGIN; memory D ALTER TABLE dl.test ALTER COLUMN id TYPE BIGINT; memory D UPDATE dl.test SET val = 'X' WHERE id = 1; ================================================================= ==83726==ERROR: AddressSanitizer: heap-use-after-free on address 0x6160001cffb8 at pc 0x00010bf6c580 bp 0x00016f1a3cf0 sp 0x00016f1a3ce8 READ of size 1 at 0x6160001cffb8 thread T5 #0 0x00010bf6c57c in duckdb::LogicalType::operator==(duckdb::LogicalType const&) const types.cpp:2071 #1 0x000106c89ab8 in duckdb::StatisticsPropagator::CanPropagateCast(duckdb::LogicalType const&, duckdb::LogicalType const&) propagate_cast.cpp:31 #2 0x00010a635dcc in duckdb::TryCastTableFilter(duckdb::TableFilter const&, duckdb::MultiFileIndexMapping&, duckdb::LogicalType const&) multi_file_column_mapper.cpp:1014 duckdb#3 0x00010a632458 in duckdb::MultiFileColumnMapper::CreateFilters(std::__1::map<unsigned long long, std::__1::reference_wrapper<duckdb::TableFilter>, std::__1::less<unsigned long long>, std::__1::allocator<std::__1::pair<unsigned long long const, std::__1::reference_wrapper<duckdb::TableFilter>>>>&, duckdb::ResultColumnMapping&) multi_file_column_mapper.cpp:1104 ``` I don't have too much knowledge on `MultiFileColumnMapper`, but considering (1) the invalid memory access is 1 byte; (2) stacktrace code location more or less indicates its logical type reference stored within `MultiFileColumnMapper` gets invalid. Turning it into value fixes the ASAN complaint.
