feat(compiler): Add sourceSpan and keySpan to TemplateBinding (#35897)

Browse Source 
This commit adds fine-grained text spans to TemplateBinding for microsyntax expressions.

1. Source span
   By convention, source span refers to the entire span of the binding,
   including its key and value.
2. Key span
   Span of the binding key, without any whitespace or keywords like `let`

The value span is captured by the value expression AST.

This is part of a series of PRs to fix source span mapping in microsyntax expression.
For more info, see the doc https://docs.google.com/document/d/1mEVF2pSSMSnOloqOPQTYNiAJO0XQxA1H0BZyESASOrE/edit?usp=sharing
