If we use a variable watchpoint with a condition using a scope variable,
if we go out-of-scope, the watpoint remains active which can the
expression evaluator to fail to parse the watchpoint condition (because
of the missing varible bindings).
This was discovered after `watchpoint_callback.test` started failing on
the green dragon bot.
This patch should address that issue by setting an internal breakpoint
on the return addresss of the current frame when creating a variable
watchpoint. The breakpoint has a callback that will disable the watchpoint
if the the breakpoint execution context matches the watchpoint execution
context.
This is only enabled for local variables.
This patch also re-enables the failing test following e1086384e584.

Reverting https://reviews.llvm.org/D151366 until Ismail has a chance
to look at the ubuntu CI test failures and can reland.
This reverts commit 7c847ac4bd1bd8a89c7fbb4581328fa8cb0498f1.

This test started failing on the green-dragon bot, but after some
investigation, it doesn't have anything to do with Lua.
If we use a variable watchpoint with a condition using a scope variable,
if we go out-of-scope, the watpoint remains active which can the
expression evaluator to fail to parse the watchpoint condition (because
of the missing varible bindings).
For now, we should disable this test until we come up with a fix for it.

As Pavel pointed out, on Apple Silicon "b main" stops at a point after
the variable has already been initialized. This patch updates the test
case to avoids that. I've also split the test into separate files so its
easier to reproduce the individual scenarios without having to build any
shared state.

Fix the nonsensical error messages for when breakpoint and watchpoint
callbacks are not supported.
