Fix 'occured' -> 'occurred' typos in backends and exir tracer (#18905)

Nine error messages used the misspelled `occured`:

- `backends/apple/mps/runtime/MPSDevice.mm:141` — additionally had a
duplicated `occured occured` (`An error occured occured while compiling
library %d`).
- `backends/cadence/hifi/operators/op_quantized_matmul_out.cpp` × 3
-
`backends/cadence/hifi/operators/op_quantized_matmul_asym8uxasym8u_asym8u_out.cpp`
× 3
-
`backends/cadence/hifi/operators/op_quantized_matmul_asym8sxasym8s_asym8s_out.cpp`
× 3
- `exir/tracer.py` — torchdynamo internal-error format string

All `ET_CHECK_MSG` and printf-style messages reach end users in build /
runtime error output, and the dynamo tracer message is logged on every
dynamo trace failure. Python `ast.parse` clean for the touched
tracer.py; .cpp/.mm changes are string-literal-only with no logic
touched.
