Fixes #154846

And apply throughout the code base.

Lines appearing after preprocessor conditional blocks (like `#endif`)
were not having their qualifiers reordered by `QualifierOrder`, while
lines inside the conditional blocks were processed correctly.

The issue was that tokens on lines following preprocessor directives
have `MustBreakBefore` = `true`. The qualifier alignment logic was
breaking immediately upon encountering any token with `MustBreakBefore`
= `true`, preventing analysis of the entire line.

The fix allows processing to continue when `MustBreakBefore` = `true` on
the first token of a line, since this is expected behavior (the token
legitimately starts a new line). Only tokens with `MustBreakBefore` =
`true` that appear mid-line will cause the analysis loop to break.

These are identified by misc-include-cleaner.  I've filtered out those
that break builds.  Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.

Remove FormatToken::isSimpleTypeSpecifier() and call
Token::isSimpleTypeSpecifier(LangOpts) instead.
