fix(types): add missing SIMD variants to Bun.Build.CompileTarget type (#26248)

Browse Source 
## Summary

- Adds missing SIMD variants to the `Build.Target` TypeScript type
- The runtime accepts targets like `bun-linux-x64-modern` but TypeScript
was rejecting them
- Generalized the type to use `${Architecture}` template where possible

## Test plan

- [x] Added regression test in `test/regression/issue/26247.test.ts`
that validates all valid target combinations type-check correctly
- [x] Verified with `bun bd test test/regression/issue/26247.test.ts`

Fixes #26247
