Substrate tracing primitives and macros.

To trace functions or individual code in Substrate, this crate provides [within_span] and [enter_span]. See the individual docs for how to use these macros.

Note that to allow traces from wasm execution environment there are 2 reserved identifiers for tracing Field recording, stored in the consts: WASM_TARGET_KEY and WASM_NAME_KEY - if you choose to record fields, you must ensure that your identifiers do not clash with either of these.

Additionally, we have a const: WASM_TRACE_IDENTIFIER, which holds a span name used to signal that the 'actual' span name and target should be retrieved instead from the associated Fields mentioned above.
