internal/lsp: run go mod vendor exclusively to avoid file contention

Running go mod vendor can result in vendor/modules.txt being transiently
deleted while it is being updated. On Windows this introduces potential
problems with file locking, if modules.txt is being read by another go
process, such as an ongoing package load.

Change the command to use RunGoCommandPiped, which executes serially
within the gopls process.

For golang/go#49646
