This sections uses generated alias guids from COM server section. This way
ProgID -> CLSID mapping returns generated guid, not the real one. ProgID string
is stored too, aligned.
- WinRT activatable class section is a plain buffer with following format:
<section header>
<module names[]>
<index[]>
<data[]> --- <class name>
<data>
Header is fixed length structure - struct strsection_header,
contains classes count;
Index is an array of fixed length index records, each record is
struct string_index.
All strings in data itself are WCHAR, null terminated, 4-bytes aligned.
All offsets are relative to section itself.
