Add test for #75158

[osa1]

This also shifts some type-size related tests into a new directory, so that we keep the number of files at the root down.

Closes #75158

[osa1]

Need to move the test to somewhere else. It should support build-fail. Any ideas where @Mark-Simulacrum ?

[Mark-Simulacrum]

Let's create src/test/ui/limits perhaps, and move this test and the related tests there, at least:

• src/test/ui/huge-array-simple-32.rs
• src/test/ui/huge-enum.rs
• src/test/ui/huge-array-simple-64.rs
• src/test/ui/issues/issue-17913.rs
• src/test/ui/consts/issue-55878.rs
• src/test/ui/huge-struct.rs
• src/test/ui/lint/issue-69485-var-size-diffs-too-large.rs

(Found with rg 'too big for' src/test/ui -t rust -c, but not manually checked for being a similar error)

cc @petrochenkov #73494

[osa1]

@Mark-Simulacrum I moved the tests you mention a bunch of others that seem to be checking type size overflows to the new dir ui/limits.

The test was failing on 32-bit as the limits are different there. Per conventions I added -64 suffix to the test name and skipped it on 32-bit.
