Merge 'Add support for soundex() function' from flaneur

add [soundex](https://www.sqlite.org/lang_corefunc.html#soundex ) scalar
function.
it seems that sqlite did not enable `soundex()` function by default
unless build it with `SQLITE_SOUNDEX`, while the sqlite in the ci
workflow did not enable it. this pr skipped the test over `soundex()`
temporarily in the `scalar-function.test` file.

Merge 'Add bitwise vdbe ops' from Preston Thorpe
...
Love the project, been following your blog posts for quite a while now.
I asked on Discord prior to submitting this, just because I didn't see a
specific issue for this feature... but if this PR is out of scope for
contributors, feel free to close it as I just had a good time hacking on
it.
This PR adds support for `BitAnd`, `BitOr`, and `BitNot` operators in
the vdbe, as well as unary expressions applied to aggregate functions;
which was needed in order to have `BitNot` support the same tests that
the other operators had.
*Also added unary negation of function calls, because since unary ops
were added, I figured adding support for the other existing unary
operator might be in scope, but lmk if not.
Let me know if there is any more tests or documentation to add/improve.

Merge 'Add support for CASE expressions.' from Alex Miller
...
There's two forms of case:
CASE (WHEN [bool expr] THEN [value])+ (ELSE [value])? END
which checks a series of boolean conditions, and:
CASE expr (WHEN [expr] THEN [value})+ (ELSE [value])? END
Which checks a series of equality conditions.
This implements support for both. Note that the ELSE is optional, and
will be equivalent to `ELSE null` if not specified.
sqlite3 gives the implementation as:
```
sqlite> explain select case a WHEN a THEN b WHEN c THEN d ELSE 0 END from casetest;

Merge 'Add last_insert_rowid() function' from Krishna Vishal
...
- Changed `Cursor` trait to be able to get access to `root_page`
- SQLite only updates last_insert_rowid for non-schema inserts. So we
check if the `InsertAwait` is not for `root_page` before updating
rowid
In SQLite it looks like this:
```
sqlite> EXPLAIN SELECT last_insert_rowid();
addr opcode p1 p2 p3 p4 p5 comment

In limbo it will look like this:
