[clang-format] Do not break before long string literals in protos

Summary:
This patch is a follow-up to r323319 (which disables string literal breaking for
text protos) and it disables breaking before long string literals.

For example this:
```
keyyyyy: "long string literal"
```
used to get broken into:
```
keyyyyy:
"long string literal"
```

While at it, I also enabled it for LK_Proto and fixed a bug in the mustBreak code.

[clang-format] Adds space around angle brackets in text protos

Summary:
This patch adds spaces around angle brackets in text proto Google style.
Previously these were detected as template openers and closers, which happened
to have the expected effect. Now we detect them as scope openers and closers
similarly to the way braces are handled in this context.

I investigated using something different than Cpp11BracedListStyle, but it turns out it's what we want and also the java and js styles also depend on that.

[clang-format] Fixes indentation of inner text proto messages

Summary:
Consider the text proto:
```
message {
sub { key: value }
}
```
Previously the first `{` was TT_Unknown, which caused the inner message to be
indented by the continuation width. This didn't happen for:
```
message {
sub: { key: value }
}
```
This is because the code to mark the first `{` as a TT_DictLiteral was only
considering the case where it marches forward and reaches a `:`.

This patch updates this by looking not only for `:`, but also for `<` and `{`.

[clang-format] Ignore UnbreakableTailLength sometimes during breaking

Summary:
This patch fixes an issue where the UnbreakableTailLength would be counted towards
the length of a token during breaking, even though we can break after the token.

For example, this proto text with column limit 20
```
# ColumnLimit: 20 V
foo: {
bar: {
bazoo: "aaaaaaa"
}
}
```
was broken:
```
# ColumnLimit: 20 V
foo: {
bar: {
bazoo:
"aaaaaaa"
}
}
```
because the 2 closing `}` were counted towards the string literal's `UnbreakableTailLength`.

Summary:
This patch fixes the indentation of the code pattern `key <...>`and `key {...}` in text protos.
Previously, such line would be alinged depending on the column of the previous
colon, which usually indents too much.

I'm gonna go ahead and commit this since it's a straightforward bugfix.
