perf(#10923): CSS Modules のクラス名をインライン化する (#10930)

* perf(#10923): unwind css module class name * perf(#10923): support multiple components * refactor: clean up * refactor(#10923): avoid `useCssModule()` * fix(#10923): allow direct literal class name * fix(#10923): avoid computed class name * fix(#10923): allow literal keys * fix(#10923): typo * fix(#10923): invalid class names * chore: test * revert: test This reverts commit 5c7ef366eceebe8ba260efa4d5d675f6c1775c45. * fix(#10923): hidden tale * perf(#10923): also unwind scoped css contained components * perf(#10923): `normalizeClass` AOT compilation --------- Co-authored-by: syuilo <Syuilotan@yahoo.co.jp>
