[bazel] Rewrite overlay handling to starlark (#170000)
Starlark is perfectly capable of doing what we need and this avoids the
dependency on a host Python
[lldb/Target] Track containing StackFrameList to avoid circular dependencies (#170226)
This change adds tracking of the StackFrameList that produced each frame
by storing a weak pointer (m_frame_list_wp) in both `StackFrame` and
`ExecutionContextRef`.
When resolving frames through `ExecutionContextRef::GetFrameSP`, the
code now first attempts to use the remembered frame list instead of
immediately calling `Thread::GetStackFrameList`. This breaks circular
dependencies that can occur during frame provider initialization, where
creating a frame provider might trigger `ExecutionContext` resolution,
which would then call back into `Thread::GetStackFrameList()`, creating
an infinite loop.
The `StackFrameList` now sets m_frame_list_wp on every frame it creates,
and a new virtual method `GetOriginatingStackFrameList` allows frames to
expose their originating list.

* Use the LFS_IFDIRTY flag to keep track of whether the Ifile has
ungathered changes during checkpoint. Modify LFS_WRITESEGENTRY and
make a new LFS_WRITEIENTRY macro to help track this. Prevents
an infinite loop in lfs_writeinode, previously caught with a panic.
* Fix a false-positive "negative bytes" panic when writing inodes into
the same segment they were in before, and consolidate the accounting
logic into new function lfs_subtract_inode.
* Ensure that we do not clean any inodes that were unavailable during
the first pass of cleaning, so that we never need to mix cleaning and
non-cleaning blocks (except for the Ifile) when writing.
* Straighten out the logic in lfs_writefile to make it more readable.
* Include IMNT_WANTRDONLY in tests for closing out writes, not just
IMNT_UNMOUNT.
* Keep track of whether the kernel cleaner is active on a file system
