Refactor QWasmEventTranslator for added readability

Change listing:
- change names of abbreviated structures/variables (e.g. KeyTbl
-> WebToQtKeyCodeMappings)
- add constants for commonly used magic strings ("Dead", StringTerminator)
- use common idioms for common tasks (find_if, std::optional)
- use binary search as facilitated by the sorted array instead of a full
search - this optimizes the code at no cost
- remove dead code (double translateEmscriptKey in
QWasmEventTranslator::getKey, remove sticky dead key support as it was
write-only, remove the dead setIsMac and g_usePlatformMacSpecifics,
remove the dead getWindowAt).
- cull the public interface on QWasmEventTranslator as some functions are
only used internally (translateEmscriptKey)
- simplify / shorten functions by short-circuiting
- modernize definitions (= default)
- auto-format the changes using clang-format

The file is now much easier to read and understand.
