Responses to #90012 seem to allow @rust-lang/wg-const-eval to decide on use of const_eval_select, so we can make core::slice::from_raw_parts[_mut] const :)


This PR marks the following APIs as const:

// core::slice
pub const unsafe fn from_raw_parts<'a, T>(data: *const T, len: usize) -> &'a [T];
pub const unsafe fn from_raw_parts_mut<'a, T>(data: *mut T, len: usize) -> &'a mut [T];

Resolves #90011

Make `core::slice::from_raw_parts[_mut]` const

Responses to rust-lang#90012 seem to allow `@rust-lang/wg-const-eval` to decide on use of `const_eval_select`, so we can make `core::slice::from_raw_parts[_mut]` const :)
