cmake: drop redundant opening/closing `.*` from `MATCH` expressions

Also from a corresponding `REPLACE` expression.

CMake matches expressions anywhere within the value without an explicit
`.*`.

https://cmake.org/cmake/help/latest/command/if.html#matches
https://cmake.org/cmake/help/latest/command/string.html#regex-match

Closes #15773
