quic: Rename kMaxValue histogram sentinels in QUIC enums

QUIC_CLIENT_HISTOGRAM_ENUM expects an exclusive enum count for
its enum_size parameter. PathValidationReason and
MultiPortStatusOnMigration defined an extra enumerator named
kMaxValue without an explicit value, making it act as an exclusive
count rather than an inclusive maximum value.

In Chromium, 3-argument UMA_HISTOGRAM_ENUMERATION() is changing to
disallow logging enums that define kMaxValue to prevent conflating a
count with a max value. Rename these boundary sentinels to kNumReasons
and kNumStatuses to reflect their semantics and prevent compile
errors when consumed by Chromium histogram macros.
