std.static_string_map: Cast length of input for runtime initialization

[burgerindividual]

In the init function, there seems to be a missing @intCast for the length of the input to a u32, which breaks usage of the function with a slice input. This should be possible, and the change reflects the cast in initComptime.

Thanks for catching that. Would you mind adding a small test which would otherwise fail without this patch?

EDIT:

Maybe adjust this test, casting slice to an actual slice:

why is the len field u32 instead of usize?

This was done as an optimization in #19719

i noticed a speedup reducing the size of the struct from 48 to 32
bytes and thus use u32s instead of usize for all length fields

I updated the test case and verified that it does not compile without the additional @intCast, and with the cast it runs successfully.

Thanks! Looks good.
