[CodeComplete] Tweak code completion for `typename`.

Summary:
Currently, clangd always completes `typename` as `typename qualifier::name`, I think the current behavior is not useful when the code completion is triggered in `template <>`. So I tweak it to `typename identifier`.

[CodeComplete] Include more text into typed chunks of pattern completions

Summary:
To allow filtering on any of the words in the editors.
In particular, the following completions were changed:
- 'using namespace <#name#>'
Typed text before: 'using', after: 'using namespace'.
- 'else if (#<condition#>)'
Before: 'else', after: 'else if'.
- 'using typename <#qualifier#>::<#name#>'
Before: 'using', after: 'using typename'.

This slightly improves the final output. Should not affect clients that

[CodeComplete] Consistently break after '{' in multi-line patterns

Summary:
Completion can return multi-line patterns in some cases, e.g.

for (<#init#>; <#cond#>; <#inc#>) {
<#body#>
}

[CodeComplete] Consistently break after '{' in multi-line patterns

Summary:
Completion can return multi-line patterns in some cases, e.g.

for (<#init#>; <#cond#>; <#inc#>) {
<#body#>
}

However, most patterns break the line only before closing brace,
resulting in code like:

namespace <#name#> { <#decls#>
}

While some (e.g. the 'for' example above) are breaking lines after the
opening brace too.

This change ensures all patterns consistently break after the opening
brace, this leads to nicer UX when using those in an actual editor.

[CodeComplete] Do not complete self-initializations

Summary:
Removes references to initialized variable from the following completions:

int x = ^;

Handles only the trivial cases where the variable name is completed
immediately at the start of initializer or assignment, more complicated
cases aren't covered, e.g. these completions still contain 'x':

// More complicated expressions.
int x = foo(^);
int x = 10 + ^;
// Other kinds of initialization.
int x{^};
int x(^);
// Constructor initializers.
struct Foo {
Foo() : x(^) {}
int x;
};

We should address those in the future, but they are outside of the scope of
this initial change.

Improve code completion by introducing patterns for the various C and
C++ grammatical constructs that show up in top-level (namespace-level)
declarations, member declarations, template declarations, statements,
expressions, conditions, etc. For example, we now provide a pattern
for

static_cast<type>(expr)

when we can have an expression, or

using namespace identifier;

when we can have a using directive.

Also, improves the results of code completion at the beginning of a
top-level declaration. Previously, we would see value names (function
names, global variables, etc.); now we see types, namespace names,
etc., but no values.
