Bug 1822194 - Vendor libwebrtc from 36f668c8bb

Upstream commit: https://webrtc.googlesource.com/src/+/36f668c8bb821dc622ceef89f905f2a3290879d5
    Use default values provided by PartitionAlloc instead of hard-coded ones

    https://crrev.com/c/2738677 added a variable to
    base/allocator/partition_allocator/build_overrides/partition_alloc.gni
    and this change prevents chromium roll.

    Instead of adding a variable to WebRTC's partition_alloc.gni,
    import that file. This will avoid repeating these operations in the
    future.

    Bug: None
