[Space Lua] Implement native Lua pattern matching engine (#1838)

Browse Source 
* Add Lua *pattern matching engine* (`pattern.ts`) that directly ports
  `lstrlib.c` semantics.

* Integrate the new engine into the `string` API for `find`, `match`,
  `gmatch`, and `gsub` functions.

* Add a pattern test suite (`pattern_test.lua`) covering character
  classes, repetition quantifiers, edge cases as well as error
  conditions.

* Refactor `string_test.lua` to remove duplicated pattern tests that
  are now covered by the pattern test suite.

* Fix `string.rep` separator support.

* Fix `string.sub` index handling.

* Remove the obsolete `string_test2.lua` file.
