Subject: [experiment] add alternative wasm sqlite3 implementation available
 via build-tag (#2863)

This allows for building GoToSocial with [SQLite transpiled to WASM](https://github.com/ncruces/go-sqlite3) and accessed through [Wazero](https://wazero.io/).

+// Oflag are flags used for FS.OpenFile. Values, including zero, should not be
+// interpreted numerically. Instead, use by constants prefixed with 'O_' with
+// special casing noted below.
+//
+// # Notes
+//
+//   - O_RDONLY, O_RDWR and O_WRONLY are mutually exclusive, while the other
+//     flags can coexist bitwise.
+//   - This is like `flag` in os.OpenFile and `oflag` in POSIX. See
+//     https://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html

+// This is a subset of oflags to reduce implementation burden. `wasip1` splits
+// these across `oflags` and `fdflags`. We can't rely on the Go `os` package,
+// as it is missing some values. Any flags added will be defined in POSIX
+// order, as needed by functions that explicitly document accepting them.
