Update some SDK docs from MVP (#3212)

Summary:

doc changes including 
1. Remove instruction for Buck because we're moving away from it and just use CMake now and future;
2. Remove Coming soon for the realized feature;
3. Formatting.

-    i). ***Buck***
-
-    In Buck, users simply depend on the etdump target which is:
-    ```
-    //executorch/sdk/etdump:etdump_flatcc
-    ```
-    When compiling their binary through Buck, users can pass in this buck config to enable the pre-processor flag. For example, when compiling `sdk_example_runner` to enable ETDump generation, users compile using the following command:
-    ```
-    buck2 build -c executorch.event_tracer_enabled=true examples/sdk/sdk_example_runner:sdk_example_runner
-    ```
-
-    ii). ***CMake***
-
-    In CMake, users add this to their compile flags:
-    ```
-    -DET_EVENT_TRACER_ENABLED
-    ```
-
-    This flag needs to be added to the ExecuTorch library and any operator library that the users are compiling into their binary. For reference, users can take a look at `examples/sdk/CMakeLists.txt`. The lines of of interest are:
-    ```
-    target_compile_options(executorch PUBLIC -DET_EVENT_TRACER_ENABLED)
-    target_compile_options(portable_ops_lib PUBLIC -DET_EVENT_TRACER_ENABLED)
