Use shorter names in internal TARGET_PROPERTY expressions
The change in commit 2f708f5d65 (Make internal TARGET_PROPERTY generator
expressions more robust, 2018-09-07, v3.13.0-rc1~94^2~4) introduced
globally unique names in synthesized `$<TARGET_PROPERTY:...>` generator.
We used the pattern `<target-name>::T<pointer-to-generator-target>` to
guarantee uniqueness. However, in projects that require many such
expressions to be generated there was a measurable increase in runtime.
We had included the target name in the synthesized genex only for human
reference during debugging. It is not necessary. Switch to the pattern
`:<pointer-to-generator-target>` to shorten the name. Also hand-roll a
hex-print loop instead of using sprintf. Together these optimizations
get at least some of the time back.
Issue: #18964
