atbrakhi 630e4b75da devtools: Implement frame scoped evaluation (#42936)
When paused at a breakpoint, hovering over local variables now shows
their value. Previously `eval` used `executeInGlobal()` which could not
access local scope, so hovering showed `ReferenceError` instead of the
actual value.

Testing: Added a new test
Fixes: Part #36027
