OpenPype: use semver module for version resolution

[antirotor]

Feature

This PR is adding semver module and utilizing it for version resolution. OpenPypeVersion is extending semver.VersionInfo. It is adding path and staging attributes to it and slightly changing how staging is working.

3.0.0-rc.1+staging < 3.0.0-rc1
3.0.0+staging < 3.0.0
3.0.0-rc.1+foo-staging < 3.0.0
3.0.0 < 3.0.0 (with path set)
3.0.0 (with zip as path) < 3.0.0 (with dir as path)

This is also adding itself to version list detected during startup, so when we are running newer version then those already installed, current running version will be used.

resolves #1505

This fixes following:

• If currenly running OpenPype version is higher then the one found installed locally (or in shared folder), current one is used without installing it.
• When version zip is deleted after it is extracted.
• Shared versions are now joined by those find locally and highest is selected from these
• Build time is printed after build.
