Add Go 1.27 support

The language_server_windows_x64.exe used by Google's antigravity AI IDE employs an unreleased version declared as go1.27rc. In IDA, its complete string is "go1.27-20260209-RC00 cl/867831283 +86f7959aa6 X:boringcrypto,simd". Therefore, we can assume that 1.27 is about to move from rc to `release`. We can then use the latest content of the master branch at https://github.com/golang/go to implement version 1.27 support. The following[ PR ](https://github.com/mandiant/GoReSym/pull/89)is one I completed.

Start by reviewing PR #89 and the latest master branch of golang/go, which the issue identifies as the basis for Go 1.27 support. Compare the existing version-support approach with the upstream 1.27 changes; done means the tool recognizes and supports the new Go version.
