* types/Coin: compile and reuse Regexps to reduce massive RAM+CPU burn

Fixes a resource (CPU+RAM) burn from recompiling Regexps which would
consume 1.2+MiB of RAM and 1.1ms per ParseCoin invocation, which means
that 1,000 invocations would consume 1.2GiB of RAM and >1second.

With the change, ParseCoin now takes 3.2us down from 1.1ms, with
dramatic results:

name         old time/op    new time/op    delta
ParseCoin-8    1.04ms ± 4%    0.00ms ± 1%  -99.69%  (p=0.000 n=9+10)

name         old alloc/op   new alloc/op   delta
ParseCoin-8    1.20MB ± 0%    0.00MB ± 0%  -99.94%  (p=0.000 n=10+10)

name         old allocs/op  new allocs/op  delta
ParseCoin-8     17.8k ± 0%      0.0k ± 0%  -99.89%  (p=0.000 n=10+10)

Fixes #7986.

* replace the CoinDenomRegex variable with SetCoinDenomRegex() (#7998)
