This commit cleans up the recently refactored aya-bpf-macros
to be a little easier to maintain:
Cosmetic changes:
1. The flow of the parse function is the same in each file
2. Useless if !attrs.is_empty() guards were removed
3. The compile error when cgroup_sock programs have an invalid
attach_type was in the wrong location
Functional changes:
1. Remove pop_required_arg. All args are optional and making them
required was a mistake on my part. We may revisit this later.
2. Rename pop_arg to pop_string_arg
3. Implement pop_bool_arg to allow for single idents to be mixed with
our key/value pair syntax in macro attributes. This is used for
`sleepable` and `frags` in XDP programs.

The aya-bpf-macros needed refactoring for:
1. Ease of testing
2. To be consistent with when we use K/V args vs. idents
3. To deprecate the use of `name` to change the exported name of a
function - we now use the symbol table.
