Currently, the spans of expressions are recorded only relative to the
template node that they reside in, not their source file.
Introduce a `sourceSpan` property on expression ASTs that records the
location of an expression relative to the entire source code file that
it is in. This may allow for reducing duplication of effort in
ngtsc/typecheck/src/diagnostics later on as well.

This is a prerequisite to fix a bug in template completions whereby
completion of the string `ti` for the variable `title` results in
`tititle`.
This is because the position where the completion is requested is used
to insert the completion text. This is incorrect. Instead, a
`replacementSpan` should be used to indicate the span of text that needs
to be replaced. Angular's own `Completion` interface is insufficient to
hold this information. Instead, we should just use ts.CompletionEntry.
Also added string enum for `CompletionKind`, which is similar to
ts.ScriptElementKind but contains more info about HTML entities.

The TemplateInfo type is an extension of AstResult, but it is not
necessary at all. Instead, improve the current interface for AstResult
by removing all optional fileds and include the TemplateSource in
AstResult instead.

Part 3/3 of language-service refactoring:
Change all language service APIs to return TS value since Angular LS
will be a proper tsserver plugin. This reduces the need to transform
results among Angular <--> TS <--> LSP.
PR Close#32116
This PR changes the language service to work in two different modes:
1. TS + Angular
Plugin augments TS language service to provide additonal Angular
information. This only works with inline template and is meant to be
used as a local plugin (configured via tsconfig.json).
2. Angular only
Plugin only provides information on Angular templates, no TS info at
all. This effectively disables native TS features and is meant for
internal use only.
Default mode is `angularOnly = false` so that we don't break any users
already using Angular LS as local plugin.
As part of the refactoring, `undefined` is removed from type aliases
because it is considered bad practice.
go/tsstyle#nullableundefined-type-aliases
```
Type aliases must not include |null or |undefined in a union type.
Nullable aliases typically indicate that null values are being passed
around through too many layers of an application, and this clouds the
source of the original issue that resulted in null. They also make it
unclear when specific values on a class or interface might be absent.

Currently, template expressions and statements have their location
recorded relative to the HTML element they are in, with no handle to
absolute location in a source file except for a line/column location.
However, the line/column location is also not entirely accurate, as it
points an entire semantic expression, and not necessarily the start of
an expression recorded by the expression parser.
To support record of the source code expressions originate from, add a
new `sourceSpan` field to `ASTWithSource` that records the absolute byte
offset of an expression within a source code.

This PR fixes a bug in autocompletion for @Input/@Output decorator with
an alias. The current implementation ignores the alias.

When tokenizing markup (e.g. HTML) element attributes
can have quoted or unquoted values (e.g. `a=b` or `a="b"`).
The `ATTR_VALUE` tokens were capturing the quotes, which
was inconsistent and also affected source-mapping.
Now the tokenizer captures additional `ATTR_QUOTE` tokens,
which the HTML related parsers understand and factor into their
token parsing.

Removes the tsickle dependency added when tsickle was added to the
transform compiler.
Added a test to ensure stray dependencies are not added and no
errors are introduced during module flattening.
Reworked some of the code so asserts are no longer necessary.
Added additional and potentially redundant checks
Added checks where the null checker found real problems.
