I/O behavior variables

Environment variables for handling default I/O behavior.

Variable	Description
`ALLINEA_NEVER_FORWARD_STDIN`	Do not forward the `stdin` of the `perf-report` command `stdin` to the program under analysis, even if you are running without the user interface. By default, Arm® Performance Reports only forwards `stdin` when running without the user interface.
`ALLINEA_ENABLE_ALL_REPORTS_GENERATION`	Enables the option in Arm® Performance Reports to generate all types of results at the same time, using the `all` extension.
