Tracing for wasm with bridging to native (#6916)

* implement events handling, implement parent_id for spans & events

* add events to sp_io::storage

* update test

* add tests

* adjust limit

* let tracing crate handle parent_ids

* re-enable current-id tracking

* add test for threads with CurrentSpan

* fix log level

* remove redundant check for non wasm traces

* remove duplicate definition in test

* Adding conditional events API

* prefer explicit parent_id over current,

enhance test

* limit changes to client::tracing event implementation

* remove From impl due to fallback required on parent_id

* make tracing codecable

* replace with global tracing

* new tracing interface

* impl TracingSubscriber in client

* implement access to global TracingSubscriber from primitives

* span for wasm

* increment towards Wasm Tracing Subscriber implementation

* increment, remove sp-tracing from runtime-interface

* increment, it compiles

* attained original functionality with new mechanism

* implement remaining TracingSubscriber functions

* remove spans from decl_module

* add handling for encoded values

* Revert "replace with global tracing"

This reverts commit 8824a60deea54d9b437407a21c8ceaf6a1902ee5.

* Wasm Side Tracing

* tracing on wasm

* enable tracing wasm on node-runtime

* export all the macros in std

* tracing subscriber on wasm-side only

* pass spans and events over and record them

* reactivate previous code and  cleanup

* further cleaning up

* extend the span macros, activate through executive

* tracking the actual extrinsic, too

* style

* fixing tests

* spaces -> tabs

* attempting to reactivate params

* activate our tests in CI

* some passing

* tests passing

* with core lazy

* global tracer for wasm side with pass over

* fixing metadata referencing

* remove const_fn feature requirement

* reenable dispatch traces

* Merge DebugWriter from tracing and frame-support, move to sp-std

* remove dangling fixme

* Docs for tracing primitives

* cleaning up a bit more

* Wasm interface docs

* optimise docs.rs setup

* adding low level storage tracing events into frame

* add custom Debug impl for WasmMetadata

* cloning profiler

* adding info about cloning profiler

* using in-scope for within calls

* proper time tracing, cleaning up println

* allow to disable tracing on runtime_interface-macro

* disable tracing for wasm-tracing-interface

* simplify wasm-tracing-api

* update client to new interface

* fixing docs and tests for sp-tracing

* update integration tests

* re-activating enter_span

* dropping FIXME, it's documented

* fix formatting

* fix formatting

* fix imports

* more debug info

* inform wasm about it being disabled by returning 1

* only one tracer, but enabled multi-all support

* make trait pub again for tests

* Apply suggestions from code review
