Currently we have a few sections that does not support specifying no keys for them. E.g. it is required that one of "Content", "Size" or "Entries" key is present. There is no reason to have this restriction. We can allow this and emit an empty section instead. This opens road for a simplification and generalization of the code in `validate()` that is discussed in the D89039 thread. Depends on D89039. Differential revision: https://reviews.llvm.org/D89391

## Check how yaml2obj produces .stack_sizes sections.
|
|
|
|
## Test the following cases when the .stack_sizes Content field is specified:
|
|
## 1) We can produce a .stack_sizes section from a description with
|
|
## a valid section content.
|
|
## 2) We can produce an incorrect .stack_sizes section from a description with
|
|
## a broken (truncated) section content.
|
|
## 3) We can produce an empty .stack_sizes section from a description with
|
|
## empty section content.
