Pete Bacon Darwin 304a12f027 feat(compiler): support skipping leading trivia in template source-maps (#30095)
Leading trivia, such as whitespace or comments, is
confusing for developers looking at source-mapped
templates, since they expect the source-map segment
to start after the trivia.

This commit adds skipping trivial characters to the lexer;
and then implements that in the template parser.

Pawel Kozlowski dafbbf8b64 fix(core): parse incorrect ML open tag as text (#29328)
This PR alligns markup language lexer with the previous behaviour in version 7.x:
https://stackblitz.com/edit/angular-iancj2

While this behaviour is not perfect (we should be giving users an error message
here about invalid HTML instead of assuming text node) this is probably best we
can do without more substential re-write of lexing / parsing infrastructure.

This PR just fixes #29231 and restores VE behaviour - a more elaborate fix will
be done in a separate PR as it requries non-trivial rewrites.

Pawel Kozlowski f2dc32e5c7 fix(core): don't wrap `<tr>` and `<col>` elements into a required parent (#29219)
BREAKING CHANGE:

Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.

This meachanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that has rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:

```html
<projecting-tr-inside-tbody>
  <tr>...</tr>
</projecting-tr-inside-tbody>
```

In the above example the `<projecting-tr-inside-tbody>` component culd be "surprised" to see additional
`<tbody>` elements inserted by Angular HTML parser.

Pete Bacon Darwin f7c867ebc2 fix(ivy): correctly tokenize escaped characters in templates (#28978)
Previously the start of a character indicated by an escape sequence
was being incorrectly computed by the lexer, which caused tokens
to include the start of the escaped character sequence in the
preceding token. In particular this affected the name extracted
from opening tags if the name was terminated by an escape sequence.
For example, `<t\n>` would have the name `t\` rather than `t`.

This fix refactors the lexer to use a "cursor" object to iterate over
the characters in the template source. There are two cursor implementations,
one expects a simple string, the other expects a string that contains
JavaScript escape sequences that need to be unescaped.

Pete Bacon Darwin 76979e12c9 refactor(compiler): remove not-null operator hack from lexer (#28978)
The parts of a token are supposed to be an array of not-null strings,
but we were using `null` for tags that had no prefix. This has been
fixed to use the empty string in such cases, which allows the `null !`
hack to be removed.

Pete Bacon Darwin c0dac184cd fix(compiler): markup lexer should not capture quotes in attribute value (#28055)
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.

Pete Bacon Darwin 2424184d42 feat(compiler): support tokenizing escaped strings (#28055)
In order to support source mapping of templates, we need
to be able to tokenize the template in its original context.
When the template is defined inline as a JavaScript string
in a TS/JS source file, the tokenizer must be able to handle
string escape sequences, such as `\n` and `\"` as they
appear in the original source file.

This commit teaches the lexer how to unescape these
sequences, but only when the `escapedString` option is
set to true.  Otherwise there is no change to the tokenizing
behaviour.

Pete Bacon Darwin eeb560ac88 feat(compiler): support tokenizing a sub-section of an input string (#28055)
The lexer that does the tokenizing can now process only a part the source
string, by passing a `range` property in the `options` argument. The
locations of the nodes that are tokenized will now take into account the
position of the span in the context of the original source string.

This `range` option is, in turn, exposed from the template parser as well.

Being able to process parts of files helps to enable SourceMap support
when compiling inline component templates.

Pete Bacon Darwin 673ac2945c refactor(compiler): use `options` argument for parsers (#28055)
This commit consolidates the options that can modify the
parsing of text (e.g. HTML, Angular templates, CSS, i18n)
into an AST for further processing into a single `options`
hash.

This makes the code cleaner and more readable, but also
enables us to support further options to parsing without
triggering wide ranging changes to code that should not
be affected by these new options.  Specifically, it will let
us pass information about the placement of a template
that is being parsed in its containing file, which is essential
for accurate SourceMap processing.

Victor Berchet 0ebd577db4 refactor(compiler): Drop support for the deprecated `<template>`. Use `<ng-template>` instead (#22783)
BREAKING CHANGE:

The `<template>` tag was deprecated in Angular v4 to avoid collisions (i.e. when
using Web Components).

This commit removes support for `<template>`. `<ng-template>` should be used
instead.

BEFORE:

    <!-- html template -->
    <template>some template content</template>

    # tsconfig.json
    {
      # ...
      "angularCompilerOptions": {
        # ...
        # This option is no more supported and will have no effect
        "enableLegacyTemplate": [true|false]
      }
    }

    <!-- html template -->
    <ng-template>some template content</ng-template>
