qapi: Move duplicate collision checks to schema check()
With the recent commit 'qapi: Detect collisions in C member names', we have two different locations for detecting clashes - one at parse time, and another at QAPISchema*.check() time. Remove all of the ad hoc parser checks, and delete associated code (for example, the global check_member_clash() method is no longer needed). Testing this showed that the test union-bad-branch wasn't adding much: union-clash-branches also exposes the error message when branches collide, and we've recently fixed things to avoid an implicit collision with max. Likewise, the error for enum-clash-member changes to report our new detection of upper case in a value name, unless we modify the test to use all lower case. The wording of several error messages has changed, but the change is generally an improvement rather than a regression. No change to generated code.
