 Build/Test Tools: Introduce automated PHP compatibility checking.

 This change introduces a new Composer script, `compat` that will scan the
 codebase for (detectable) potential PHP compatibility issues using the
 `PHP_CodeSniffer` and a custom ruleset based off of the
 `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).

 The command will be run as a separate job within each Travis build. While
 many compatibility issues and false positives have already been corrected
 in this commit and other Trac tickets, there are still some remaining. For
 that reason, the job is allowed to fail while the remainder of the
 potential compatibility issues are investigated and addressed. After those
 are resolved, the job should be set as required to pass to help prevent
 new compatibility issues from being introduced.

 Props desrosj, jrf, all PHPCompatibilityWP and PHPCompatibility
 contributors.
 Fixes #46152.
