closes: #1790
Updates test_vector_distance to treat invalid inputs as non-errors,
skipping them instead. These cases aren't considered real errors, so no
explicit error handling is needed in the test.

Refactors exec_concat_ws to skip null and blob arguments instead of
inserting separators for them. Also adds a fuzz test.

Closes#2338
closes#1893
Adds some fairly extensive tests but I'll continue to add some python
tests on top of the unit tests.
## Restart:
tested ✅
- open new DB
- create table and do a bunch of inserts
- `pragma wal_checkpoint(RESTART);`
- close db file
- re-open and verify we can read the wal/repopulate the frame cache
- verify min|max frame
tested ✅
- open same DB
- add more inserts
- `pragma wal_checkpoint(RESTART);`
- do _more_ inserts
- close
- re-open
- verify checksums/max_frame are valid
- verify row count
## Truncate
tested ✅
- open new db
- create table and add inserts
- `pragma wal_checkpoint(truncate);`
- close file
- verify WAL file is empty (32 bytes, header only)
- re-open file
- verify content/row count
tested ✅
- open db
- create table and insert many rows
- `pragma wal_checkpoint(truncate);`
- insert _more_ rows
- close db file
- verify WAL file is valid
- re-open file
- verify we can read entire file/repopulate the frame cache

Closes: #2323
This PR adds support for two new vector functions:
* vector_concat(x, y) – Concatenates two vectors of the same type.
* vector_slice(x, start_index, end_index) – Extracts a subvector from
the input vector.
Notes:
* Negative start_index or end_index is not supported
