Fix ESM exports

Start by reviewing the package metadata and ESM examples named in the issue, including rc-field-form/es/utils/validateUtil.js, rc-dialog/es/Dialog/Content/Panel.d.ts, and rc-picker/es/interface.d.ts. Check how the rc-* packages expose their lib and es trees under the shown NodeNext tsconfig. Done means ESM imports and type imports across the react-component modules resolve without the listed TypeScript, runtime, or esbuild errors.

There are many errors to fix in all react-component modules for them to work well when imported from an ESM module.

Importing things from "rc-???" & types from "rc-???/es/..." from an ESM module with recommended (less fault-tolerant / strictest) TS config should not raise any error.

My tsconfig.json contains:

{
  "compilerOptions": {
    "moduleResolution": "NodeNext",
    "module": "NodeNext",
    "skipLibCheck": false,
    "skipDefaultLibCheck": false,
    "allowImportingTsExtensions": false,
    "allowSyntheticDefaultImports": false,
    "strict": true,
    "verbatimModuleSyntax": true,
    "isolatedModules": true
  },
}

Origin of errors:

• ESM files in "rc-???/es/..." must have .d.mts or .mjs extension, or a package.json containing {"type":"module"} must be added to the folder
• in "rc-???/es/..." do not import any file from CJS exports of a module, there should not have any import ... from 'rc-???/lib/...'; => import will fail if (and it would be a good thing) imported module restricts its /lib/ path to only CJS requires (exportsfield in package.json)
• in "rc-???/es/..." any relative import (specifier or expression) in a .d.ts or .js should point to a file (not a directory) and have a file extension => TS error since modules are resolved as any
• there should be no comment between /*#__PURE__*/ comment and the function call, cf rc-field-form/es/utils/validateUtil.js => esbuild error during build
• modules with no default export (such as react) should not be imported using import Module from 'module' but instead with import * as Module from 'module', cf rc-dialog/es/Dialog/Content/Panel.d.ts or rc-picker/es/interface.d.ts => TS error with allowSyntheticDefaultImports disabled and runtime error without a bundler that fakes a default import
• TS looks for types through the main field of package.json, even when module is imported from an ESM, so package.json should be patched with:

-  "main": "./lib/index",
-  "module": "./es/index",
+  "exports": {
+    ".": {
+      "types": {
+        "import": "./es/index.d.ts",
+        "default": "./lib/index.d.ts"
+      },
+      "import": "./es/index.js",
+      "default": "./lib/index.js"
+    },
+    "./es/*": {
+      "types": {
+        "import": "./es/*"
+      },
+      "import": "./es/*"
+    },
+    "./lib/*": {
+      "types": {
+        "require": "./lib/*"
+      },
+      "require": "./lib/*"
+    }
+  },
