[clang-format] Revert breaking stream operators to previous default (#89016)

Reverts commit d68826dfbd98, which changes the previous default behavior
of always breaking before a stream insertion operator `<<` if both
operands are string literals.

Also reverts the related commits 27f547968cce and bf05be5b87fc.

[clang-format] Add BreakFunctionDefinitionParameters option (#84988)

This adds an option to break function definition parameters, putting
them on the next line after the function's opening paren.

function definition parameters be on their own lines.

[clang-format] Fix anonymous reference parameter with default value (#86254)

When enabling alignment of consecutive declarations and reference right
alignment, the needed space between `& ` and ` = ` is removed in the
following use case.

Problem (does not compile)
```
int a(const Test &= Test());
double b();
```

Expected:
```
int a(const Test & = Test());
double b();
```

Test command:

```
echo "int a(const Test& = Test()); double b();" | clang-format -style="{AlignConsecutiveDeclarations: true, ReferenceAlignment: Right}"
```

[clang-format] Fix clang-format issue with 'new' and 'delete' keywords in C files (#85470)

This resolves an issue in clang-format where `new` and `delete` were
incorrectly formatted as keywords in C files. The fix modifies
`TokenAnnotator::spaceRequiredBetween` to handle `new` and `delete` when
used as identifiers for function pointers in structs in C code.

[clang-format] Fix crash in TokenAnnotator (#82349)

The while loop on line 3814 can cause a segmentation fault getting the
Next field on a nullptr. This is because further down, on line 3823,
there is another for loop, which assigns Tok to Tok->Next in its
initializer. This for loop has a condition to check if the result of
that isn't null. If it is, the loop is skipped and we drop back out to
the outer loop, except, now Tok is null, and we try to dereference it
without checking first.

This patch adds a defensive check that returns if Tok->Next is null
before we make it to the second for loop.

Fix an issue where the lambda body left brace could sometimes fail to be

Now, when BraceWrapping.BeforeLambdaBody is enabled, if the brace is not
wrapped, we prevent breaks in the lambda body.
