Fixes https://github.com/llvm/llvm-project/issues/53430.
Initially, I had a quick and dirty approach, but it led to a myriad of special cases handling comments (that may add unwrapped lines).
So I added TT_RecordLBrace type annotations and it seems like a much nicer solution.
I think that in the future it will allow us to clean up some convoluted code that detects records.

With config:
```
AllowShortFunctionsOnASingleLine: Inline
NamespaceIndentation: All
```
The code:
```
namespace Test
{
void f()
{
return;
}
}
```
was incorrectly formatted to:
```
namespace Test
{
void f() { return; }
}
```
since the function `f` was considered being inside a class/struct/record.
That's because the check was simplistic and only checked for a non-zero indentation level of the line starting `f`.

- Easier to debug (since you don't go through operator[] everytime)
* TheLine->First != TheLine->Last follows since last is a l brace and

Currently the lambda body indents relative to where the lambda signature is located. This instead lets the user
choose to align the lambda body relative to the parent scope that contains the lambda declaration. Thus:
someFunction([] {
lambdaBody();
});
will always have the same indentation of the body even when the lambda signature goes on a new line:
someFunction(
[] {
lambdaBody();
});
whereas before lambdaBody would be indented 6 spaces.

The current logic for access modifiers in classes ignores the option 'MaxEmptyLinesToKeep=1'. It is therefore impossible to have a coding style that requests one empty line after an access modifier. The patch allows the user to configure how many empty lines clang-format should add after an access modifier. This will remove lines if there are to many and will add them if there are missing.

This commit removes the old way of handling Whitesmiths mode in favor of just setting the
levels during parsing and letting the formatter handle it from there. It requires a bit of
special-casing during the parsing, but ends up a bit cleaner than before. It also removes
some of switch/case unit tests that don't really make much sense when dealing with
Whitesmiths.

Adds support for coding styles that make a separate indentation level for access modifiers, such as Code::Blocks or QtCreator.
The new option, `IndentAccessModifiers`, if enabled, forces the content inside classes, structs and unions (“records”) to be indented twice while removing a level for access modifiers. The value of `AccessModifierOffset` is disregarded in this case, aiming towards an ease of use.
======
The PR (https://bugs.llvm.org/show_bug.cgi?id=19056) had an implementation attempt by @MyDeveloperDay already (https://reviews.llvm.org/D60225) but I've decided to start from scratch. They differ in functionality, chosen approaches, and even the option name. The code tries to re-use the existing functionality to achieve this behavior, limiting possibility of breaking something else.

This revision aims to help that by introducing an `IndentPragmas` style, the aim of which is to keep the pragma at the current level of scope
```
for (int i = 0; i < 5; i++) {

// clang-format on
for (int j = 0; j < 5; j++) {

Summary:
The MultiLine option in BreakBeforeBraces was only handling standard
control statement, leading to invalid indentation with for each macros:
Previous behavior:
/* invalid: brace should be on the same line */
Q_FOREACH(int a; list)
{
foo();
}
/* valid */
Q_FOREACH(int longVariable;
list)
{
foo();
}
To fix this, simply add the TT_ForEachMacro kind in the list of
recognized control statements for the multiline option.

This patch fixes bug #44192
When clang-format is run with option AllowShortBlocksOnASingleLine, it is expected to either succeed in putting the short block with its control statement on a single line or fail and leave the block as is. When brace wrapping after control statement is activated, if the block + the control statement length is superior to column limit but the block alone is not, clang-format puts the block in two lines: one for the control statement and one for the block. This patch removes this unexpected behaviour. Current unittests are updated to check for this behaviour.

Found a bug introduced with BraceWrappingFlags AfterControlStatement MultiLine. This feature conflicts with the existing BeforeCatch and BeforeElse flags.
For example, our team uses BeforeElse.
if (foo ||
bar) {
doSomething();
}
else {
doSomethingElse();
}
If we enable MultiLine (which we'd really love to do) we expect it to work like this:
if (foo ||
bar)
{
doSomething();
}
else {
doSomethingElse();
}
What we actually get is:
if (foo ||
bar)
{
doSomething();
}
else
{
doSomethingElse();

Summary:
Change the BraceWrappingFlags' AfterControlStatement from a bool to an enum with three values:
* "Never": This is the default, and does not do any brace wrapping after control statements.
* "MultiLine": This only wraps braces after multi-line control statements (this really only happens when a ColumnLimit is specified).
* "Always": This always wraps braces after control statements.
The first and last options are backwards-compatible with "false" and "true", respectively.
The new "MultiLine" option is useful for when a wrapped control statement's indentation matches the subsequent block's indentation. It makes it easier to see at a glance where the control statement ends and where the block's code begins. For example:
```
if (
foo
&& bar )
{
baz();
}
```
vs.
```
if (
foo
&& bar ) {
baz();
}
```
Short control statements (1 line) do not wrap the brace to the next line, e.g.
```
if (foo) {
bar();
} else {
baz();
}
```
