[Clang][Sema] Fix a bug on type constraint checking (#84671)

Try to fix https://github.com/llvm/llvm-project/issues/84368
When visiting class members in
`TemplateDeclInstantiator::VisitClassTemplateDecl` during
`Sema::InstantiateClass`, we miss to set attribute of friend declaration
if it is(`isFriend` is true). This will lead to
`Sema::AreConstraintExpressionsEqual` return false when invoked in
`MatchTemplateParameterKind`. Because it makes
`Sema::getTemplateInstantiationArgs` returns incorrect template
argument(`MultiLevelTemplateArgumentList`). When we handle
`CXXRecordDecl` In `Sema::getTemplateInstantiationArgs`, friend
declaration(its parent context is `FileContext`) makes us to choose
`LexicalDeclContext` not `DeclContext` and this is what we want.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
