[Feature]: Support for Isolated Declarations in TS 5.5

[chenjiahan]

What problem does this feature solve?

Since SWC already supports Isolated Declarations in TS 5.5, Rslib can provide option to enable it to speed up dts generation.

swc-project/swc#9086

What does the proposed API look like?

• Detect tsconfig.json#isolatedDeclarations and enable it by default.
• Provide an option to enable / disable it, like dts. isolated

Currently, swc-loader does not ship emitIsolatedDts but swc-cli do. We need to do some processing in Rspack's built-in swc-loader to emit the result of transform during build process.

And isolated declarations produce the same result with tsc's bundleless dts, we can also support using isolated emit dts for type bundle with api-extractor.
