Summary:
Some jobs in the next diff in stack (D48229150) fail with the following message:
```
stderr: In file included from xplat/caffe2/c10/cuda/CUDACachingAllocator.cpp:9:
xplat/caffe2/c10/util/static_tracepoint.h:4:6: error: 'TORCH_DISABLE_SDT' is not defined, evaluates to 0 [-Werror,-Wundef]
!TORCH_DISABLE_SDT
```
When porting USDT macros to PyTorch in D47159249, I must have not hit a codepath which treated warnings as errors during testing.
This diff fixes the issue by first checking whether the `TORCH_DISABLE_SDT` macro is defined before trying to access it in the `static_tracepoint.h` header.
Test Plan:
Similar to D47159249, tested the following macro on test scripts with `libbpf` USDTs:
* `CAFFE_DISABLE_SDT`

Summary: Rename static tracepoint macros to better describe their targeted usage.
Test Plan:
Same as for D47159249:
Tested the following macros on test scripts with libbpf USDTs:
* `CAFFE_SDT`
* `CAFFE_DISABLE_SDT`
* `CAFFE_SDT_WITH_SEMAPHORE`

Summary: Moving static tracepoint macros header to a location where it can be easily used by various PyTorch components (`c10/utill`).
