llbsolver: add filter+limit support to history listen

[tonistiigi]

Allows picking which history records should be returned instead of always transferring all of them. Filtering only applies to completed records with EarlyExit=true.

Supported filters are:

	// ref == ~= !=
	// startedAt > < >= <=
	// completedAt > < >= <=
	// status == ~= != (running, complete, error, canceled)
	// duration > < >= <=
	// repository == ~= != // special filter by vcs:source attribute that can be used as a project selector
