Renaming of Usage Table related variables and types.

Browse Source 
[ Merge of http://go/wvgerrit/164077 ]

This CL makes major changes to the names of variables and types that
are related to the usage table, header, entries, entry indexes, and
other related data.

The renaming followed these rules:
1)  "Usage table header" will exclusively refer to the header blob
    that is OEMCrypto specific.  The CDM class "UsageTableHeader"
    is the CDM-layer's abstraction around the "usage table" concept.
    The name has been updated to reflect that.
2)  The "Cdm" prefix is only used for the CDM-specific data types for
    the usage table and entry info.  It has been removed from
    OEMCrypto-specific types.
    - UsageTableHeader -> CdmUsageTable
    - CdmUsageTableHeader -> UsageTableHeader
    - CdmUsageEntry -> UsageEntry
3)  The "usage_" prefix has been removed from variables when the usage
    table or usage entries are the subject of the function or class.
4)  UsageEntryIndex is the type for entry indexes, instead of directly
    using uint32_t.  This matches how we wrap other types in
    "wv_cdm_types.h"
5)  Changed entry "number" to entry "index".
6)  Vectors of elements have been renamed to be either pluralized or
    have a suffix "_list".
7)  "Usage info" was occasionally being used to refer to the usage
    table or entries generally, rather than specifically secure-stop.
    - CryptoSession::HasUsageInfoSupport() -> HasUsageTableSupport()

The most major change is that the files "usage_table_header*" have
been renamed to be "cdm_usage_table*".
