[eas cli] Tar creation on windows: force the owner write bit on for directories

[sswrk]

Why

When a directory is set as read-only in NTFS, this works different than read-only directory in POSIX – read-only directory in Windows doesn't stop you from creating files inside it. In POSIX, read-only directory means that you can't create files in that directory. Now, when we're creating a tar in Windows, Node.js sees the mode of read-only directories as 0o555. When extracting this tar on a worker, we're seeing an error because it's forbidden to create files in such directory.

Alternative to #3234
Fixes #3319

How

Conditionally add the onWriteEntry hook on tar creation when the OS is Windows. The hook forces the owner write bit on for directories.

Test Plan

I tested the fix in Windows 11. First, I attempted to run a build with nested read-only directories in my project. This has failed on extracting the tar in the worker. Then I tried with the changes from this PR applied, the build has succeeded.
