WASM --enable-wasm-strip now skips lots of LO code

... resulting in a stripped-down, Writer-only build to decrease
the resulting WASM bytecode size.

It removes the following code from the build:
* All other major modules: Base, Calc, Chart, Draw, Impress and
Math and related writerperfect filters
* The premultiply tables
* The (auto-)recovery functionality
* All accessibility (but not the accessibility document checker)
* The LanguageGuess component
* EPUB support
* The start center / BackingWindow
* The TipOfTheDay functionality
* The splash screen communication

Currently crashs with anything different then soffice --writer.
Closing the document also still crashes.

FYI: many of these features are now behind ENABLE_WASM_STRIP_*
defines, but they normally don't work on their own, globally!
That's because we started with stripping the main components.
