Reuse GELU implementation from PyTorch core

[swolchok]

Stack from ghstack (oldest at bottom):

• Remove ExecuTorch copy of Vectorized #7042
• -> Reuse GELU implementation from PyTorch core #7041
• Use c10 version of half/bfloat16 in executorch #7040
• Bump ExecuTorch's PyTorch nightly pin to dev20241121 #7044

kernels/optimized doesn't need to support embedded systems, so it can just take a header-only dep on PyTorch.

Note that, because we will pick up Sleef internally and ignore it
externally thanks to ATen vec, this PR gets to enable optimized GELU in OSS.

Testing: CI to make sure this doesn't break mobile build modes; happy to take advice on anything not currently covered that might break.
