Fixes#16134
* Add a warning when the misuse of `reset` in an `error:boundary` causes an error to be thrown when flushing the boundary content
* Prevent uncaught errors to make test fails when they are expected and are fired during template effects flush
* reset should just be a noop after the first call
* correctly handle errors inside boundary during reset
* handle errors in the correct boundary

#16270 removed a condition which seemed to keep passing the corresponding test, but it actually introduced a regression since the PROPS_IS_UPDATED is always set when accessors should be created, which is the case by default in legacy mode tests. Setting accessors to false in the test reveals the regression, so this reverts that part of the refactoring
* fix: use fine grained for template if the component is not explicitly in legacy mode

fixes#14532
This removes the `reactive_declaration_non_reactive_property` warning altogether. The first version caused many false positives at compile time. The refined runtime version (introduced in #14192) was hoped to fix this, but it turns out we now get loads of false positives at runtime.
