Fix: Display Bool's size as 1 byte in crystal tool hierarchy, not 0

[HertzDevil]

This is a more general fix than #8273 that works for any LLVM integer type whose bit width is not a multiple of 8 (although Crystal only uses i1).

@HertzDevil There are some CI failures which seem to originate from this change.

Apparently this is breaking the interpreter because Crystal::FileModules previously had size 0 and now have size 1. The i1 comes here because FileModule < NonGenericModuleType:

crystal/src/compiler/crystal/codegen/llvm_typer.cr

Lines 248 to 251 in 52b8e3b

	private def create_llvm_type(type : NonGenericModuleType | GenericClassType, wants_size)
	# This can only be reached if the module or generic class don't have implementors
	@llvm_context.int1
	end

This was ultimately introduced in 08fa6cd. If a module type truly has no includers then it is effectively NoReturn, which corresponds to @llvm_context.void. This is probably the correct interpretation but I am not 100% sure

EDIT: this broke codegen specs

[HertzDevil]

We are doing the right thing here. The file-private scope type should never have been passed around and some checks in the interpreter are most likely inconsistent with normal codegen
