Move the rest of testing1.js into tester1.js and eliminate the dependency on jaccwabyt_test.c. Extend the list of default config-related #defines in sqlite3-wasm.c and reorganize them for maintainability.

Non-numeric conversions include:
- `string` (args): has two different semantics in order to
accommodate various uses of certain C APIs (e.g. output-style
strings)...
- `string` or `utf8` (args): has two different semantics in order
to accommodate various uses of certain C APIs
(e.g. output-style strings)...
- If the arg is a string, it creates a _temporary_ C-string to
pass to the exported function, cleaning it up before the
wrapper returns. If a long-lived C-string pointer is
required, that requires client-side code to create the
string, then pass its pointer to the function.
- If the arg is a string, it creates a _temporary_
UTF-8-encoded C-string to pass to the exported function,
cleaning it up before the wrapper returns. If a long-lived
C-string pointer is required, that requires client-side code
to create the string, then pass its pointer to the function.
- Else the arg is assumed to be a pointer to a string the
client has already allocated and it's passed on as
a WASM pointer.
- `string` (results): treats the result value as a const C-string,
copies it to a JS string, and returns that JS string.
- `string` or `utf8` (results): treats the result value as a
const C-string, encoded as UTF-8, copies it to a JS string,
and returns that JS string.
- `string:free` (results): treats the result value as a non-const
C-string, ownership of which has just been transfered to the
caller. It copies the C-string to a JS string, frees the
C-string, and returns the JS string. If such a result value is
NULL, the JS result is `null`. Achtung: when using an API which
returns results from a specific allocator, e.g. `my_malloc()`,
this conversion _is not legal_. Instead, an equivalent conversion
which uses the appropriate deallocator is required. For example:
