Require a space in `match (..)`

Problem/Motivation

Normally, we ask that a space is put between a control structure keyword and the opening parentheses.
This is the case for `if (..)`, `foreach (..)` etc, and is enforced by the phpcs rules.

However, it is not currently enforced for `match (..)`.
In fact, we see it with and without the space:

With space:

~/projects/d8/www $ ag --count "(return|=) match \(" core/
core/tests/Drupal/Tests/Core/Cache/ChainedFastBackendFactoryTest.php:1
core/lib/Drupal/Core/Config/Schema/Mapping.php:1
core/lib/Drupal/Core/StringTranslation/ByteSizeMarkup.php:1
core/modules/system/system.install:1
core/modules/block_content/tests/src/Functional/Rest/BlockContentResourceTestBase.php:2
core/modules/block_content/src/BlockContentAccessControlHandler.php:1
core/modules/field_ui/tests/src/FunctionalJavascript/ManageFieldsTest.php:1
core/modules/jsonapi/tests/src/Functional/BlockContentTest.php:1

Without space:

~/projects/d8/www $ ag --count "(return|=) match\(" core/
core/lib/Drupal/Core/Database/StatementWrapperIterator.php:3
core/lib/Drupal/Core/Database/StatementPrefetchIterator.php:1
core/modules/pgsql/src/Driver/Database/pgsql/Schema.php:1
core/modules/field_ui/src/Form/EntityDisplayModeFormBase.php:3
core/modules/jsonapi/tests/src/Functional/FileTest.php:1
core/modules/ckeditor5/src/Plugin/Validation/Constraint/SourceEditingRedundantTagsConstraintValidator.php:1
core/modules/file/tests/src/Functional/Rest/FileResourceTestBase.php:1

Benefits

Consistency..

Three supporters required

1. https://www.drupal.org/u/larowlan (2023-12-06)
2. https://www.drupal.org/u/dww (2023-12-05)
3. https://www.drupal.org/u/jonathan1055 (2023-12-13)

Proposed changes

https://www.drupal.org/docs/develop/standards/php/php-coding-standards#c...
Explicitly mention `match (..)` as a control statement.

A match statement should have a space between the match keyword and the opening parenthesis.

return match ($value) {
  5 => 'win',
  default => 'loss',
};

Note that "match" can also be a method name.
In that case, no space should be added:

return $this->match($value);

Remaining tasks

1. Create this issue in the Coding Standards queue, using the defined template
2. Add supporters
3. Create a Change Record
4. Review by the Coding Standards Committee
5. Coding Standards Committee takes action as required
6. Tagged with 'Needs documentation edits' if Core is not affected
7. Discussed by the Core Committer Committee, if it impacts Drupal Core
8. Documentation updates
   1. Edit all pages
   2. Publish change record
   3. Remove 'Needs documentation edits' tag
9. If applicable, create follow-up issues for PHPCS rules/sniffs changes
