Drop PHP 7.3

[phil-davis]

Description

This is a PoC demonstrating the changes needed to drop PHP 7.3

Note: because of issue #40103 I cannot do composer update in this PR, or in core master. So the PHP dependencies may be a bit out-of-date here. After that issue is resolved (for example, by merging the guzzle v7 PR), then I can rebase this and update the dependencies.

composer found the following dependencies that it could update:

php /usr/local/bin/composer install
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Package operations: 0 installs, 4 updates, 2 removals
  - Removing laminas/laminas-zendframework-bridge (1.4.1)
  - Removing container-interop/container-interop (1.2.0)
  - Upgrading psr/container (1.1.1 => 1.1.2): Extracting archive
  - Upgrading laminas/laminas-servicemanager (3.7.0 => 3.11.2): Extracting archive
  - Upgrading laminas/laminas-filter (2.12.0 => 2.14.0): Extracting archive
  - Upgrading laminas/laminas-inputfilter (2.12.1 => 2.13.0): Extracting archive

apps/files_external/3rdparty is also updated.

Other things that could be done are:

• bump from phpunit v9 to v10 (if phpunit v10 gets released "soon")
• bump Symfony v4 to v5
• check other major versions of dependencies in composer.json and see what could be updated
