Revert "[clang-tidy][NFC] Remove duplicated code"

This reverts commit b6f6be4b500ff64c23a5103ac3311cb74519542f.

[clang-tidy][NFC] Remove duplicated code

Remove duplicated matchers by moving some of them to
utils/Matchers.h. Add some anonymous namespaces and
renamed some code to avoid ODR issues.

[clang-tidy][NFC] Code format - leftover after #66169

Manually formating code via clang-format after previous
commit merge.

This patch replaces uses of StringRef::{starts,ends}with with

I'm planning to deprecate and eventually remove

[clang] remove ClassScopeFunctionSpecializationDecl (#66636)

This removes the `ClassScopeFunctionSpecializationDecl` `Decl` node, and
instead uses `DependentFunctionTemplateSpecializationInfo` to handle
such declarations. `DependentFunctionTemplateSpecializationInfo` is also
changed to store a `const ASTTemplateArgumentListInfo*` to be more in
line with `FunctionTemplateSpecializationInfo`.

This also changes `FunctionDecl::isFunctionTemplateSpecialization` to
return `true` for dependent specializations, and
`FunctionDecl::getTemplateSpecializationKind`/`FunctionDecl::getTemplateSpecializationKindForInstantiation`
to return `TSK_ExplicitSpecialization` for non-friend dependent
specializations (the same behavior as dependent class scope
`ClassTemplateSepcializationDecl` & `VarTemplateSepcializationDecl`).

[clang-tidy] Improve modernize-use-emplace check

This patch improves the modernize-use-emplace check by adding support for
detecting inefficient invocations of the `push` and `push_front` methods on
STL-style containers and replacing them with their `emplace`-style equivalent.

Fixes #56996.

[clang-tidy] Add proper emplace checks to modernize-use-emplace

modernize-use-emplace only recommends going from a push_back to an
emplace_back, but does not provide a recommendation when emplace_back is
improperly used. This adds the functionality of warning the user when
an unecessary temporary is created while calling emplace_back or other "emplacy"
functions from the STL containers.

[clang-tidy][NFC] Replace many instances of std::string where a StringRef would suffice.

There's many instances in clang tidy checks where owning strings are used when we already have a stable string from the options, so using a StringRef makes much more sense.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[clang-tidy] modernize-use-emplace: Remove unnecessary make_tuple calls

Summary:
This patch makes modernize-use-emplace remove unnecessary make_ calls from push_back calls and turn them into emplace_back -- the same way make_pair calls are handled.
Custom make_ calls can be removed for custom tuple-like types -- two new options that control that are `TupleTypes` and `TupleMakeFunctions`. By default, the check removes calls to `std::make_pair` and `std::make_tuple`.

Eq.

```
std::vector<std::tuple<int, char, bool>> v;
v.push_back(std::make_tuple(1, 'A', true)); // --> v.emplace_back(1, 'A', true);
```
