This adds the enclosingDeclarationName to the beginMethod of the
parser listener.
This enables the removal BuilderFactory.currentTypeParameterScopeBuilder.

This changes the BodyBuilder to create FunctionTypeParameter instead
of FormalParameterBuilder for "parameters" in function types. This
avoids the creation of unnecessary VariableDeclaration nodes
function types.
The types of these VariableDeclarations where created before the type
variable scope was completed, introducing an artificial dependency on
the pending nullability computation.

When the parser sends events to the listener some events has a pair of
parameters, `beginToken` and `endToken`. Most of these are constructed
in such a way that the `beginToken` is the first token and the
`endToken` is the last token in that construct. This is for instance the
case with `endClassDeclaration`.
It was, however, not the case for `endMetadata` where `endToken` instead
was the next token *not* in the metadata.
In this CL I've found a changed the following to point to the last token
in the construct instead of the next token not in the construct and
renamed the parameter where it made sense:
* `endAssert` --- and renamed `semicolonToken` (which only pointed to
a semicolon for statements) to `endToken`.
* `endAwaitExpression`
* `endConstLiteral` --- and renamed `token` to `endToken`
* `endConstructorReference`
* `endFieldInitializer` --- and renamed `token` to `endToken`
* `endForIn`
* `endForInBody` --- and renamed `token` to `endToken`
* `endForStatement`
* `endForStatementBody` --- and renamed `token` to `endToken`
* `endFunctionExpression` --- and renamed `token` to `endToken`
* `endInitializer` --- and renamed `token` to `endToken`
* `endInitializers`
* `endInvalidAwaitExpression`
* `endMetadata`
* `endSwitchCase`
* `endTopLevelDeclaration` --- and renamed `nextToken` to `endToken`
* `endWhileStatement`
* `endWhileStatementBody` --- and renamed `token` to `endToken`
* `handleNoConstructorReferenceContinuationAfterTypeArguments`
In the few places in listeners where these values were used I've mostly
updated to do e.g. `endToken.text!` to retain the current behavior.

The listener API for variable patterns is split into three separate
functions, to handle the three separate behaviors:
- `handleAssignedVariablePattern` for variable names appearing in an
assignment context (these assign to an existing variable upon a
successful match).
- `handleDeclaredVariablePattern` for variable declarations appearing
in a declaration or matching context (these cause a new variable
name to come into scope).
- `handleWildcardPattern` for wildcards in any context (these don't
capture the matched value).
Also, responsibility is shifted to the parser for reporting the
following error conditions:
- VariablePatternKeywordInDeclarationContext (e.g.
`var (var x) = ...;`)
- PatternAssignmentDeclaresVariable (e.g. `[x, var y] = ...;`)
Previously these errors were detected by the implementations, and
weren't fully covering all possible error scenarios.
In the case of VariablePatternKeywordInDeclarationContext, the
listener method `handleDeclaredVariablePattern` is called instead of
`handleAssignedVariablePattern`. This ensures that no tokens are
dropped from the analyzer AST. The CFE uses the `inAssignmentPattern`
argument of `handleDeclaredVariablePattern` to distinguish this error
recovery case from a legitimate declared variable pattern.

This allows the parser to parse constant patterns at lower precedence
level in order to recognize more expressions in this context. To
support this, _parsePrecedenceExpressionLoop special cases a few cases
that should _not_ be parsed as expression in a constant pattern context.
Closes#50996
