-----------
[libpas] Clean up Windows implementation
https://bugs.webkit.org/show_bug.cgi?id=313512
rdar://175725768
Reviewed by Marcus Plutowski.
1. Scan libpas pthread stub on Windows and fix obvious issues.
2. We reintroduce is_symmetric flag to pas page allocation. When it is set,
commit and decommit are paired explicitly (asymmetric protocol does not
require explicit commit) as Windows has commit charge limit which
does not exits on POSIX environment.
