[mlir] Add a new debug action framework.

This revision adds the infrastructure for `Debug Actions`. This is a DEBUG only
API that allows for external entities to control various aspects of compiler
execution. This is conceptually similar to something like DebugCounters in LLVM, but at a lower level. This framework doesn't make any assumptions about how the higher level driver is controlling the execution, it merely provides a framework for connecting the two together. This means that on top of DebugCounter functionality, we could also provide more interesting drivers such as interactive execution. A high level overview of the workflow surrounding debug actions is
shown below:

*   Compiler developer defines an `action` that is taken by the a pass,
    transformation, utility that they are developing.
*   Depending on the needs, the developer dispatches various queries, pertaining
    to this action, to an `action manager` that will provide an answer as to
    what behavior the action should do.
*   An external entity registers an `action handler` with the action manager,
    and provides the logic to resolve queries on actions.

The exact definition of an `external entity` is left opaque, to allow for more
interesting handlers.

This framework was proposed here:

[mlir] Add support for DebugCounters using the new DebugAction infrastructure

DebugCounters allow for selectively enabling the execution of a debug action based upon a "counter". This counter is comprised of two components that are used in the control of execution of an action, a "skip" value and a "count" value. The "skip" value is used to skip a certain number of initial executions of a debug action. The "count" value is used to prevent a debug action from executing after it has executed for a set number of times (not including any executions that have been skipped). For example, a counter for a debug action with `skip=47` and `count=2`, would skip the first 47 executions, then execute twice, and finally prevent any further executions.

This is effectively the same as the DebugCounter infrastructure in LLVM, but using the DebugAction infrastructure in MLIR. We can't simply reuse the DebugCounter support already present in LLVM due to its heavy reliance on global constructors (which are not allowed in MLIR). The DebugAction infrastructure already nicely supports the debug counter use case, and promotes the separation of policy and mechanism design philosophy.

[lldb][NFC] Don't inherit from UserID in ValueObject

ValueObject inherits from UserID which is just a bad idea:

* The inheritance gives ValueObject some member functions that are at best
  misleading (such as `Clear()` which doesn't clear any value beside `id`).

* It allows passing ValueObject to the overloaded operators for UserID (such as
  `==` or `<<` which won't actually compare or print anything in the ValueObject).

* It exposes the `SetID` and `Clear` which both allow users to change the
  internal id value.

Similar to D91699 which did the same for Process

[OpenCL] Move remaining defines to opencl-c-base.h

Move any remaining preprocessor defines from `opencl-c.h` to
`opencl-c-base.h`, such that they are shared with
`-fdeclare-opencl-builtins` too.

In particular, move:
- the `as_type` and `as_typen` definitions, and
- the `kernel_exec` and `__kernel_exec` definitions.

Also clang-format the changes.
