Fix GH-10489: run-tests.php does not escape path when building cmd (#10560)

Multiple tests had to be changed to escape the arguments in shell
commands. Some tests are skipped because they behave differently with
spaces in the path versus without. One notable example of this is the
hashbang test which does not work because spaces in hashbangs paths are
not supported in Linux.

Fix run-tests.php hanging when a worker process dies without notice (#9931)

run-tests.php with `-jN` can hang if a parallel worker dies without notice. This
can happen due to fatal errors in the worker, or if the worker is killed.

Fix run-tests.php for explicitly given test cases

The recent improvement to list skipped extensions explicitly[1] missed
to properly initialize `$ignored_by_ext` for the case where an explicit
set of test cases are given; this was not a problem previously, since
the undefined *global* variable was coerced to int. We fix this by
initializing the variable earlier.

Fix run-tests.php --no-progress flag for non-parallel testing

Add --[no-]progress option to run-tests.php (#9255)

Previously, adding the -g argument would disable progress, even locally.
Now it needs to be disabled explicitly.

[run-tests.php] Combine multiple `str_replace` calls to a single `strtr` call

Makes the replacement easier to see, neatly aligned, and only takes one function call.
This is safe because none of the combined replacement values contain tokens that would be recursively replaced.

This also improves the readability on how the regular expressions in `EXPECTF` matcher is constructed.

[run-tests.php] Replace backtick operator string literals with `shell_exec()` calls

The rationale is that `shell_exec()` is identical to the backtick operator (both of which are disabled when `shell_exec` function is disabled) makes it very clear that it is a shell execution, and eases security audits too.
