[jdk25u-dev] RFR: 8370325: G1: Disallow GC for TLAB allocation

[Goetz Lindenmaier]

I backport this for parity with 25.0.3-oracle

Trivial resolve needed in [g1CollectedHeap.cpp](https://github.com/openjdk/jdk/commit/027aea9d2e0dff29fcd00fa7074ca955066929ec#diff-9de15630db460d66fdee5ec408be02b3275a2fbf32764f9fb2910b0d1bff7e3a)
