        fix(engine): @wire() protocol reform RFC

fix: rebase issues

fix: wire-reform tests (#1524)

* fix: invalid syntax error on invalid wire param value

When a wire parameter has invalid value (eg: foo..bar, foo.bar[3]) it should (ideally) resolve in a compilation error during validation phase.

This is not possible due that platform components may have a param definition which is invalid but passes compilation, and throwing at compile time would break such components.

In such cases where the param does not have proper notation, the config generated will use the bracket notation to match the current behavior (that most likely end up resolving that param as undefined).

* fix: tests for wire reactive parameters

* fix: unit test register and WireAdapter

* fix: backward compability when adding config listener

* fix: adding general tests for wire adapter

* wip: address pr comments and lint errors

fix: reactivity of wire params (#1526)

* fix: reactivity of wire params

* wip: address review comments

and run performance

* wip: trigger perf measures

* fix: remove valueMutated pruning condition

* fix: add componentValueObserved for consistency

* fix: remove tf because of wired properties being track

before the wire reform.

* fix: ensure component rerender in compat

* fix: tf because registerDecorators happens before registerAdapter

* Revert "fix: tf because registerDecorators happens before registerAdapter"

This reverts commit b2d1a89.

* fix: wire integration tests

fix: rebase issues

fix: remove tests because wire defs is not part of the public api

of getComponentDef

fix: add test for inherited methods

fix: context in targets hierarchy

fix: add registerWireService for backward compability

it is a noop.

fix(engine): remove assertions added by mistake on rebase

fix: rebase conflicts

fix: lint errors

todos errors.

fix: add support for adapters that use wirecontextevent

fix: prefix wired element key with deprecated and remove

redundant options in descriptor
