`createTemporaryFile` overloads

== Synopses

Declared in `<bdls_filesystemutil.h>`

Create and open a new file with a name constructed by appending an automatically‐generated suffix to the specified `prefix`, and return its file descriptor open for reading and writing. A return value of `k_INVALID_FD` indicates that no such file could be created; otherwise, the name of the file created is assigned to the specified `outPath`. The file is created with permissions restricted, as closely as possible, to the caller`s userid only. If the prefix is a relative path, the file is created relative to the process current directory. Responsibility for deleting the file is left to the caller. Note that on Posix systems, if `outPath` is unlinked immediately, the file will remain usable until its descriptor is closed. Note that files created on Microsoft Windows may receive default, not restricted permissions.

Same as the overload taking `bsl::string *`, using `std::pmr::string`.
