Ports a part of Unicode's ICU in pure Kotlin and implements
Android-style plural string resource support. Fixes
JetBrains/compose-multiplatform#425.
# Changes
- Added `org.jetbrains.compose.resources.intl.{PluralCategory,
PluralRule, PluralRuleList}`, which parses and evaluates scripts in
Unicode's Locale Data Markup Langauge.
- Copied `plurals.xml` from Unicode's
[CLDR](https://github.com/unicode-org/cldr/blob/release-44-1/common/supplemental/plurals.xml).
- Added `GeneratePluralRuleListsTask`, which parses `plurals.xml` and
generates required Kotlin source codes.
- Added `PluralStringResource`, `pluralStringResource`, or
`getPluralString`, corresponding to `StringResource`, `stringResource`,
or `getString`.
- Modified `ResourcesSpec.kt` so the generated `Res` class exposes
`Res.plurals`.
# Potential Further Improvements
- [ ] Allow configuring the default language in the `compose.resources
{}` block (#4482) to determine the default pluralization rule (or just
presume English as default)
- [ ] Move the parser logic to the Gradle plugin and generate
pluralization rules in `Res` only for languages used in
`composeResources`
