Adding a new configuration to build binaries for code coverage analysis

[aneeshdk]

The build is enabled by setting the environment variable ENABLE_CODECOVERAGE. For code coveage, optimization is turned off and additional arguments are passed during linking to include more debug information.

@digitalinfinity & @abchatra can you please review this?

Why is this global?

Also I don't understand why noopt isn't just a normal flavor and requires this hacky looking special casing. Is it not possible to make noopt work like debug release and test so that this flavPathStr variable is unnecessary?

[aneeshdk]

Made it global because it is used in pre_post_util.ps1 too. Also the value can change inside other methods in the future. Noopt can be used with any flavor, so it does not exactly replace flavor string. Something like test_noopt or debug_noopt will be the more right format but I am keeping it this way for now to align with the infrastructure pieces.
