[lldb] Add support for ScriptedFrame to provide values/variables.
This patch adds plumbing to support the implementations of StackFrame::Get{*}Variable{*} on ScriptedFrame. The major pieces required are:
- A modification to ScriptedFrameInterface, so that we can actually call the python methods.
- A corresponding update to the python implementation to call the python methods.
- An implementation in ScriptedFrame that can get the variable list on construction inside ScriptedFrame::Create, and pass that list into the ScriptedFrame so it can get those values on request.
There is a major caveat, which is that if the values from the python side don't have variables attached, right now, they won't be passed into the scripted frame to be stored in the variable list. Future discussions around adding support for 'extended variables' when printing frame variables may create a reason to change the VariableListSP into a ValueObjectListSP, and generate the VariableListSP on the fly, but that should be addressed at a later time.
This patch also adds tests to the frame provider test suite to prove these changes all plumb together correctly.

[lldb] Add conversions for SBValueList and SBValue to the python bridge.
This patch adds support for:
- PyObject -> SBValueList (which was surprisingly not there before!)
- PyObject -> SBValue
- SBValue -> ValueObjectSP using the ScriptInterpreter
These three are the main remaining plumbing changes necessary before we can get to the meat of actually using ScriptedFrame to provide values to the printer/etc. Future patches build off this change in order to allow ScriptedFrames to provide variables and get values for variable expressions.

[lldb] Move ValueImpl and ValueLocker to ValueObject, NFC.
This patch moves ValueImpl and ValueLocker to ValueObject.{h,cpp}. This follows the example set in TypeImpl/SBType, where we have something that SBType uses internally that needs to be exposed in the layer below. In this case, SBValue uses ValueImpl, which wraps ValueObject. The wrapper helps avoid bugs, so we want to keep it, but the script interpreter needs to use it and said interpreter is conceptually *below* the SB layer...which means we can't use methods on SBValue.
This patch is purely the code motion part of that, future patches will actually make use of this moved code.

[clang][bytecode] Only check static lambda captures if we have to (#178452)
Call `getCaptureFields()` only if the function is static, because we
only care about the captures in that case.
workflows/release-tasks: Add missing needs tag to release-lit job (#178224)
The job references variables from the validate-tag job, so it needs to
have it listed in the 'needs' tag. This is why this job failed for the
22.1.0-rc2 release.
[CodeGen] Only use actual alloca alignment (#178361)
Remove getPrefTypeAlign calls and use only the alloca's explicit
alignment, since the type may not be semantically useful, there is no
useful reason to change alignment to support it.
The alloca's explicit alignment (from getAlign()) is already optimally
correct; we don't need to derive alignment from the allocated type.

[NFC][CodeGen] Use getAllocationSize instead of manual size computation (#178360)
Replace manual alloca size computation with `getAllocationSize` API.
This reduces dependency on `getAllocatedType` when just needed for size
and vscale queries.

[Lint] Replace getAllocatedType with getAllocationSize (#178353)
This now also handles constant array allocations (getAllocationSize
returns total size for constant array allocations, whereas the old code
explicitly excluded isArrayAllocation from linting support).

[NFCI][IRBuilder] Add CreateAllocationSize helper (#178346)
Create a new `IRBuilderBase::CreateAllocationSize` method to compute the
runtime size of an alloca as a Value*. This handles both static and
dynamic allocas by computing `ArraySize * ElementSize`, and using
CreateTypeSize to properly handle scalable vectors.
This de-duplicates code across multiple instrumentation and analysis
passes and increases consistency.

[libc][math] Refactor sqrt to header-only (#178335)
This refactors `sqrt` to be header-only, following the libc math
refactoring plan.
Part of #147386
Closes #177648
