Test emoji & INLINE BLOB values; check too many parameters error

ISSUES documented:
- emojis and other 4-octet UTF-8 characters on Android-sqlite-connector & Windows
  ref: storesafe#564
- INLINE BLOB values on Android-sqlite-connector & Windows
- In case of too many parameters the plugin reports INCORRECT error code 0
  (SQLError.UNKNOWN_ERR) while Android/iOS (WebKit) Web SQL reports
  correct error code

 - It is possible to request a SQL statement list such as "SELECT 1; SELECT 2" within a single SQL statement string, however the plugin will only execute the first statement and silently ignore the others ref: [litehelpers/Cordova-sqlite-storage#551](https://github.com/litehelpers/Cordova-sqlite-storage/issues/551)
 - It is possible to insert multiple rows like: `transaction.executeSql('INSERT INTO MyTable VALUES (?,?),(?,?)', ['Alice', 101, 'Betty', 102]);` which was not supported by SQLite 3.6.19 as referenced by [Web SQL API section 5](https://www.w3.org/TR/webdatabase/#web-sql).

 - Known issue(s) with handling of `Infinity` values (positive or negative) and certain ASCII/UNICODE characters as described below.
 - Boolean `true` and `false` values are handled by converting them to the "true" and "false" TEXT string values, same as WebKit Web SQL on Android and iOS. This does not seem to be 100% correct as discussed in: [litehelpers/Cordova-sqlite-storage#545](https://github.com/litehelpers/Cordova-sqlite-storage/issues/545)
 - Certain errors such as CREATE VIRTUAL TABLE USING bogus module are reported with error code 5 (SQLError.SYNTAX_ERR) on Android and iOS. This happens to be the case for WebKit Web SQL (Android/iOS).
 - A number of uncategorized errors are reported with error code 5 (SQLError.SYNTAX_ERR) on Android and iOS by both WebKit Web SQL and this plugin.
 - Issues with error code on Windows as well as Android with the `androidDatabaseImplementation: 2` setting described below.
 - In case of an issue that causes an API function to throw an exception (Android/iOS WebKit) Web SQL includes includes a code member with value of 0 (SQLError.UNKNOWN_ERR) in the exception while the plugin includes no such code member.
 - This plugin supports some non-standard features as documented below.
+- Results of SELECT with BLOB data such as `SELECT LOWER(X'40414243') AS myresult`, `SELECT X'40414243' AS myresult`, or reading data stored by `INSERT INTO MyTable VALUES (X'40414243')` are not consistent on Android in case the built-in Android database is used (using the `androidDatabaseImplementation: 2` setting in `window.sqlitePlugin.openDatabase`) or Windows. (These work with Android/iOS WebKit Web SQL and have been supported by SQLite for a number of years.)

 - iOS version does not support certain rapidly repeated open-and-close or open-and-delete test scenarios due to how the implementation handles background processing

+- The Android and Windows versions do not always handle four-byte UTF-8 characters emoji characters such as `\u1F603` (SMILING FACE, MOUTH OPEN) correctly ref: [litehelpers/Cordova-sqlite-storage#564](https://github.com/litehelpers/Cordova-sqlite-storage/issues/564). It is sometimes possible to store and retrieve such characters but certain operations hex conversions do not work properly with the default [Android-sqlite-connector](https://github.com/liteglue/Android-sqlite-connector) database implementation. It is suspected that such characters would be stored incorrectly in the Android and Windows versions. This is not an issue in case the built-in Android database is used (using the `androidDatabaseImplementation: 2` setting in `window.sqlitePlugin.openDatabase`)
