memfile::hp: `find_size_bytes()` fixed and tested; should change function to return `eyre::Result<usize>` instead of `Option<usize>` considering how many different failure-paths exist.

memfile::hp: Added `Mask`: Converts bytes into a suitable `MAP_HUGE_` constant via its `.raw()` method, and a suitable flag for `memfd_create()` via its `.mask()` method.
...
The above is all either `const fn` or checked, and can be bitwise OR"d together, producing a higher `Mask`, or bitwise OR"d with an arbitrary `c_uint` to produce a valid mask for `memfd_create()` (in the latter case, the OR with MFD_HUGETLB is unneeded, as `Mask` applies this itself.)

Started: `memfile::hp`: `MFD_HUGETLB` can be used when a size is known to exceed into the boundary of a hugepage. Currently in the process of writing function to collect all possible hugepage sizes and generate the correct flag masks for `memfd_create(, MFD_HUGETLB | ...)` for each one; and the smallest one that contains the known size can be used for the `memfd_create()` call (if the size fits any at all.)
...
TODO: This will be a seperate comptime feature: `hugetlb`: Extend `memfile` with the ability to allocate apporpirately sized huge-pages when input size is known to extend into them.

feature memfile: added `RawFile::open_mem()`
...
Needs testing, and the XXX comment about `memfd_create()` name lifetimes also needs testing. (If they do need to be static; `stackalloc` as a dependancy can be removed entirely, then: `DEFAULT_NAME` will be changed to a CString, function parameter `name` and `error::MemfileCreationStep::Create(name)` will be changed to `Option<&"static CStr>`.
