Code Review
This pull request modifies the GLES backend in Impeller to query and store the active uniform block data size, using the maximum of the buffer view length and the block data size when calling gl.BindBufferRange. It also introduces corresponding unit tests and mock GLES functions. The review feedback recommends clamping the retrieved block data size to at least zero to prevent potential integer underflow during type casting.

issue #187212
This clamps the minimum bound size of a UBO to GL_UNIFORM_BLOCK_DATA_SIZE. This was causing a crash in firefox's webgl2 implementation.
