fix(exports): export the calls PPSA07411 imports

PPSA07411 (Resident Evil 4) fails to load without these imports that no library exports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds one test and a TechnicalDebt entry.

 - [_fstatfs](../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) fills the FreeBSD 11 `struct statfs` of the PS5 payload SDK with the host volume that holds the file: block size, transfer size, total, free and available blocks, maximum name length and the read-only, `nosuid` and `noexec` flags (on Windows only read-only, and `f_files` and `f_ffree` are 0, as NTFS has no fixed number of files). The filesystem type number and name, mount paths, owner, filesystem id and I/O counters are left 0 or empty, since they would describe a host mount, not a console one. Sockets and pipes return `EINVAL`, as FreeBSD's `getvnode` does; a Windows descriptor that is neither a file nor a pipe throws. Stremio Plus (PPSA74126) reads the free space before a download and only logs the other fields
 - [_WStoul](../../core/libs/prx/libc/src/Strings.cpp), [_Iswctype](../../core/libs/prx/libc/src/RuneLocale.cpp) and [swscanf_s](../../core/libs/prx/libc/src/ScanningWide.cpp) (libc) - `_WStoul` is `wcstoul` and throws for a base other than 0 or 2 to 36. `_Iswctype` takes the class numbers of Dinkumware's [xwcc.h](https://github.com/superna9999/ti-cgt6x/blob/cgt6x_7_3_4/include/xwcc.h) (1 `alnum` to 11 `xdigit`, 12 `blank`) and throws for any other value, including the FreeBSD masks `wctype` returns; the numbering is not confirmed on the console's `libc.prx`. `swscanf_s` follows C11 7.29.2.2 and K.3.9.1.5, but reads the size argument as `unsigned int` like `sscanf_s` where K.3.9.1.5 specifies `rsize_t`; the console's width is unverified. A runtime-constraint violation (null buffer, format or receiving pointer) only returns `EOF`, and a too small array gets a null first element as in `sscanf_s`. A literal mismatch is a matching failure and a field that is only a prefix, such as `0x` or `1e`, does not convert, as C11 requires; FreeBSD's `vfwscanf` reports an input failure for the first and converts the second. Integers out of range are truncated from `strtoll`/`strtoull`. It throws for `%p`, `%S`, `%C`, unknown length modifiers, scanset ranges, `%n` with suppression or width, and narrow `%s`, `%c` or `%[` input that the C-locale `wcrtomb` cannot convert
 - [sceSharePlayGetCurrentConnectionInfoA](../../core/libs/prx/libSceSharePlay/Export.cpp) (libSceSharePlay) - reports no Share Play session, as the library keeps none: status 0 (DORMANT), mode 0, empty online IDs, account IDs 0 and both user IDs -1 (`SCE_USER_SERVICE_USER_ID_INVALID`). A null pointer returns `SCE_SHARE_PLAY_ERROR_INVALID_ARGS` (0x810E0001). The 72-byte `SceSharePlayConnectionInfoA` layout and the error code follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/main/src/libs/libNet.cpp) and [fpPS4](https://github.com/red-prig/fpPS4/blob/trunk/src/ps4_libsceshareplay.pas), which agree on both; KytyPS5 sets the user IDs to -1 and fpPS4 leaves them 0, and which one the console returns is not verified. KytyPS5 also returns `SCE_SHARE_PLAY_ERROR_NOT_INITIALIZED` before `sceSharePlayInitialize`; this library keeps no initialization state and does not.
