Support declarationMap for @pika/plugin-ts-standard-pkg

[Jack-Works]

Declaration map just like source map can let IDEs jump to the source file (ts) instead of .js file or .d.ts file.

I found in the source code, pika disabled the declaration map. Why?

I... don't actually know why that was disabled for all builds, maybe TS turns it on by default? Either way, that feels like something that should be configurable by the user. I'll remove that override so that anyone can configure it in their tsconfig instead

Uh, I think this fix doesn't work. It does generate dist-types/*.d.ts.map, but after the package published, the declaration maps are broken.

For example, index.d.ts.map

{
    "version": 3,
    "file": "index.d.ts",
    "sourceRoot": "",
    "sources": ["../../src/index.ts"],
    "names": [],
    "mappings": "AAAA;;;;GAIG;AACH,cAAc,gBAAgB,CAAA;AAC9B,cAAc,sBAAsB,CAAA;AACpC,cAAc,iBAAiB,CAAA"
}

After install, it will become /node_modules/package_name/dist-types/index.d.ts.map, but ../../src/index.ts doesn't contain the source file, so IDE cannot jump to the source location

I have the exact same issue. Is is possible to copy the src folder to the distributed package and then point the declaration maps to TypeScript source files in that folder?

Ah, that was probably why it was disabled then. Remind me to add a comment next time :) Thanks everyone for debugging and @kripod for creating a quick fix
