fix: Exclude framework-inferred env vars with wildcards (#11303)
### Description
Framework inference opt-out via negative env wildcards in `globalEnv`
(e.g., "globalEnv": ["!VITE_*"]) was not working as documented. As
described in https://github.com/vercel/turborepo/issues/10826,
`globalEnv` wasn't making its way to per-task contexts.
With this PR, we propagate those changes down to task execution context
to meet user expectations.
### Testing Instructions
Adding some tests around this behavior and hand tested myself.
