John Maguire afbdc87ed9 Update gvisor and bump to go1.27 (#1940)
gvisor's arm64 race-build compare-and-swap (pkg/sync/race_arm64.s)
loaded the new value into the register meant for the old one (R1
instead of R2), so it never succeeded. Sleepers could not commit to
parking and spun: under -race on arm64 every idle service netstack
busied about 14 cores, and TestService's static host lookup of
localhost missed its 250ms timeout and stalled for the 30s static_map
cadence. Fixed in gvisor 1b2946c4fa.

Go 1.27.2 is now the minimum because gvisor's go branch requires it.
golangci-lint is bumped to v2.14, the first release that can read
go1.27.2 export data.
