clang-{tools,unittests}: Stop using SourceManager::getBuffer, NFC

Update clang-tools-extra, clang/tools, clang/unittests to migrate from
`SourceManager::getBuffer`, which returns an always dereferenceable
`MemoryBuffer*`, to `getBufferOrNone` or `getBufferOrFake`, both of
which return a `MemoryBufferRef`, depending on whether the call site was
checking for validity of the buffer. No functionality change intended.

Make SourceManager::createFileID(UnownedTag, ...) take a const llvm::MemoryBuffer*

Requires making the llvm::MemoryBuffer* stored by SourceManager const,
which in turn requires making the accessors for that return const
llvm::MemoryBuffer*s and updating all call sites.

The original motivation for this was to use it and fix the TODO in
CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag
version of createFileID, and since llvm::SourceMgr* hands out a const
llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO
this way actually works, but this seems like a good change on its own
anyways.

No intended behavior change.

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] Speedup misc-static-assert.

Summary:
Speedup the misc-static-assert check by not use `stmt()` as the toplevel matcher.
The framework runs a filter on the matchers before trying them on each node and
uses the toplevel type for this.
Using `stmt()` as the toplevel causes the matcher to be run on every `Stmt` node,
even if the node doesn't match the desired types.

This change speeds up clang-tidy by ~5% in a benchmark.
