v0.3.0: Switch to WASM, rewrite build pipeline

[stepankuzmin]

• Switch to WASM, drop JS-only bundle
• Use the emscripten/emsdk Docker image to build the WASM artifact
• Use the latest available ICU 75.1 and build it from the sources
• Keep WASM artifacts in the repo
• Use Rollup as a bundler
• Provide one UMD bundle that inlines all WASM subresources as base64 string literals
• Switch to GitHub Action instead of CircleCI
• Adds local debug page run by vite

The API for the GL JS interoperability the same:

mapboxgl.setRTLTextPlugin('mapbox-gl-rtl-text.js');

// or
mapboxgl.setRTLTextPlugin(
      'node_modules/@mapbox/mapbox-gl-rtl-text/dist/mapbox-gl-rtl-text.js',
      null,
      false
);

The NPM package now exports UMD with a pending promise as a default export (see src/index.js). The promise is resolved to previously exported functions:

import rtlText from '@mapbox/mapbox-gl-rtl-text';
const {applyArabicShaping, processBidirectionalText} = await rtlText;

const arabicString = "سلام";
const shapedArabicText = applyArabicShaping(arabicString);
const readyForDisplay = processBidirectionalText(shapedArabicText, []);
